The reason is that the .osgt text files do not provide size information about the contained binary shader hence leading to a bad allocation when reading the shader data, probably size 0 ? The reader method in the responsible serializer class (serializers/osg/BinaryShader) is correct and does not need to be changed as it queries the size as expected. The writer method supports two paths(binary output .osgb and text output .osgt/.osgx). Only the text path is affected as the binary path writes the size.
I extended the writer in the text path by the size information. The results before and after the fix are shown below:
Erroneous code for binary shader in osgt file before fix:
Data {
0a

Corrected code for binary shader in osgt file after fix:

After my fix the the thrown error disappeared."
The DatabasePager now passes the Terrain pointer into the ReaderWriter's via osgDB::Options object,
rather than pushing a NodePath containing the Terrain onto NodeVisitor. This
change means that the DatabasePager nolonger needs to observer the whole NodePath and
will be lighter and quicker for it.
The change also means that ReadFileCallback can now run custom NodeVisitor's on the scene graph without
having to worry about TerrainTile's constructing scene graphs prior to the Terrain being assigned.
Also changed is the NodeVisitor::DatabaseRequestHandler which now requires a NodePath to the node that you wish
to add to rather than just the pointer to the node you wish to add to. This is more robust when handling scenes
with multiple parental paths, whereas previously errors could have occurred due to the default of picking the first
available parental path. This change means that subclasses of DatabasePager will need to be updated to use this new
function entry point.
Attached is src/osgWrappers/deprecated-dotosg/osg/Geometry.cpp. It gets the data pointer out and casts it to a pointer to the element type, rather than casting the array object itself. This seems to work."
serializers and dotosgwrappers. It includes reading/writing supports
for the two new shader types and the GL_PATCHES enum. The
setParameterfv() method is not wrapped at present because it is still
not finished.
Enum serialziers don't require back-compatibility checks if only
add/remove enum items, so I'm not going to use the new

serialization libraries. My submission mainly includes:
1. Add two new macros USE_DOTOSGWRAPPER_LIBRARY and
USE_SERIALIZER_WRAPPER_LIBRARY. Applications using static OSG must
include corresponding static-link libraries and use these two macros
to predefine native format wrappers. Please see osgstaticviewer and
present3D in the attachment for details.
2. Add a LibraryWrapper.cpp file in each
osgWrappers/deprecated-dotosg/... and osgWrappers/serializers/...
subfolder, which calls all USE_...WRAPPERS macros inside. The
LibraryWrapper file is automatically generated by the
wrapper_includer.cpp (with some slight fixes), which is also attached
for your reference. The deprecated-dotosg/osgAnimation is not included
because it doesn't us REGISTER_DOTOSGWRAPPER to define its wrappers.
3. Modify the ReaderWriterOSG.cpp to prevent calling loadWrappers()
when static build.
4. An uncorrelated fix to Serializer and ObjectWrapper.cpp, which
ensures version variables of serialziers are initialized, and
serializers out-of-version are not written to model files.

In the attached file (src/osgWrappers/deprecated-dotosg/osgParticle/IO_Particle.cpp) I have added a check for the existence of the drawable before writing it to the file.

type is supported at present. The attached osgparticleshader.cpp will
show how it works. It can also be placed in the examples folder. But I
just wonder how this example co-exists with another two (osgparticle
and osgparticleeffect)?
Member variables in Particle, including _alive, _current_size and
_current_alpha, are now merged into one Vec3 variable. Then we can
make use of the set...Pointer() methods to treat them as vertex
attribtues in GLSL. User interfaces are not changed.
Additional methods of ParticleSystem are introduced, including
setDefaultAttributesUsingShaders(), setSortMode() and
setVisibilityDistance(). You can see how they work in
osgparticleshader.cpp.
Additional user-defined particle type is introduced. Set the particle
type to USER and attach a drawable to the template. Be careful because
of possible huge memory consumption. It is highly suggested to use
display lists here.
The ParticleSystemUpdater can accepts ParticleSystem objects as child
drawables now. I myself think it is a little simpler in structure,
than creating a new geode for each particle system. Of course, the
latter is still compatible, and can be used to transform entire
particles in the world.
New particle operators: bounce, sink, damping, orbit and explosion.
The bounce and sink opeartors both use a concept of domains, and can
simulate a very basic collision of particles and objects.
New composite placer. It contains a set of placers and emit particles
from them randomly. The added virtual method size() of each placer
will help determine the probability of generating.
New virtual method operateParticles() for the Operator class. It
actually calls operate() for each particle, but can be overrode to use
speedup techniques like SSE, or even shaders in the future.
Partly fix a floating error of 'delta time' in emitter, program and
updaters. Previously they keep the _t0 variable seperately and compute
different copies of dt by themseleves, which makes some operators,
especially the BounceOperator, work incorrectly (because the dt in
operators and updaters are slightly different). Now a getDeltaTime()
method is maintained in ParticleSystem, and will return the unique dt
value (passing by reference) for use. This makes thing better, but
still very few unexpected behavours at present...
All dotosg and serialzier wrappers for functionalities above are provided.
...
According to some simple tests, the new shader support is slightly
efficient than ordinary glBegin()/end(). That means, I haven't got a
big improvement at present. I think the bottlenack here seems to be
the cull traversal time. Because operators go through the particle
list again and again (for example, the fountain in the shader example
requires 4 operators working all the time).
A really ideal solution here is to implement the particle operators in
shaders, too, and copy the results back to particle attributes. The
concept of GPGPU is good for implementing this. But in my opinion, the
Camera class seems to be too heavy for realizing such functionality in
a particle system. Myabe a light-weight ComputeDrawable class is
enough for receiving data as textures and outputting the results to
the FBO render buffer. What do you think then?
The floating error of emitters
(http://lists.openscenegraph.org/pipermail/osg-users-openscenegraph.org/2009-May/028435.html)
is not solved this time. But what I think is worth testing is that we
could directly compute the node path from the emitter to the particle
system rather than multiplying the worldToLocal and LocalToWorld
matrices. I'll try this idea later.

modifications of the osgShadow header naming styles as well. The
osgDB::Serializer header is also changed to add new Vec2 serializer
macros because of the needs of osgShadow classes. It should compile
fine on both Windows and Linux. But I have only done a few tests to
generate .osgb, .osgt and .osgx formats with these new wrappers."
few headers and the osgAnimation sources are also modified to make
everything goes well, including:
A new REGISTER_OBJECT_WRAPPER2 macro to wrap classes like
Skeleton::UpdateSkeleton.
A bug fix in the Seralizer header which avoids setting default values
to objects.
Naming style fixes in osgAnimation headers and sources, also in the
deprecated dotosg wrappers.
A bug fix for the XML support, to write char values correctly.
A small change in the osg::Geometry wrapper to ignore the
InternalGeometry property, which is used by the MorphGeometry and
should not be set by user applications.
The avatar.osg, nathan.osg and robot.osg data files all work fine with
serializers, with some 'unsupported wrapper' warnings when converting.
I'm thinking of removing these warnings by disabling related property
serializers (ComputeBoundingBoxCallback and Drawable::UpdateCallback),
which are seldom recorded by users.
By the way, I still wonder how would we handle the C4121 problem,
discussed some days before. The /Zp compile option is set to 16 in the

of OSG. I modified the osgDB::InputStream and OutputStream and the
PagedLOD wrapper as well. Now all seems to work fine with paged
scenes. I've tested with the puget terrain data and the osgdem
application from VPB:
# osgdem --xx 10 --yy 10 -t ps_texture_4k.tif --xx 10 --yy 10 -d
ps_height_4k.tif -l 8 -v 0.1 -o puget.osgb
As the ive plugin does, The PagedLOD wrapper now automatically add the
latest file path to PagedLODs' databasePath member, to help them find
correct child positions. I also changed the image storage strategy of
the OutputStream class, to store them inline by default. The osgt
extension should also work, in case the image files are also written
to the disk.

the type writing more explictly tied to the size type, with use of unsigned int as the default size. This approach
ensures that we get the same results under 32 and 64bit builds.
1. Rewrite the reading/writing exception handlers to work like the ive
plugin exceptions.
2. Write a header writing/checking function in ReaderWriterOSG2.cpp,
which may help decide if the stream is ascii or binary. The
readInputIterator() function will return null pointer if the input
file is nither osgb nor osgt format, which indicates that the old .osg
format could be used here, in case we've merged the two plugins
together.
3. Add a new ForceReadingImage option in the InputStream, which will
allocate an empty image object with the filename if specifed external
image file is missed. It may be useful for format converting in some
cases.
4. Add new osgParticle wrappers, as well as some modification to the
osgParticle headers, for instance, change isEnabled() to getEnabled().
5. Some fixes to the osg serialization wrappers."
