methods for the billboard and the camera you already take a pointer
instead of a ref_ptr."

The crash disappears if I either (1) disable the use of images with stride
in the (public) osgGeo-library, or (2) add the following bugfix to Glyph.cpp.
This combination gives me the confidence that I understand where this problem
originates from, without trying to understand the full OpenGL details.

databasePager->setUpThreads(16, 1);
We experienced problems with multiple databasepagers loading files in parallel, when two threads start to load the same file (usually a texture referenced by multiple models). The second thread to add the file to the cache (sometimes) manages to do so while the refcount from the cached object still is zero, causing the object loaded to be destroyed.
Sometimes the second thread manages to ref() the object before Referenced::signalObserversAndDelete does the final recount check, causing a warning:
"Warning Referenced::signalObserversAndDelete(,,) doing delete with _refCount=1"
With a deleted object added to the scenegraph we get some undesired results, I think the program only crashes if the object was a Node, and just has some untextured surfaces if it was a texture, but I'm not completely sure.
Attached is a modified version of the Registry.cpp, returning the object in cache and let the duplicate loaded object to be destroyed.
A more efficient option would be to add some sort of blocking entry to the objectcache to stop the second thread from reading the file, and just wait until the first thread added it to the cache. If you think that's worthwile we would be happy to implement that version. A bit tricky to implement and test, that's why I submit a simple version that stops my program from crashing."

"I noticed that Text3D objects would change there z alignment depending on the alignment mode. I'm not sure if this was intentional or just a simple mistake. My expectation was that the front of the object would always stay aligned to the 0 z-plane, regardless of the alignment mode. I've attached an updated version that retains a consistent z-alignment."
"I just now noticed another issue with Text3D objects. It was not properly computing the bounding box when non-axis aligned rotations were being applied. In this case all corners of the bounding box need to be transformed in order to get the correct containing box. I've attached the updated file."
"The incorrect bounding box problem also applies to regular Text objects. I've attached the fix for that as well as the original Text3D fix."

optimizations to reduce cpu overhead:
1) Avoid a load-hit-store in UpdateBone. b->getMatrixInBoneSpace()
returns the same matrix that was just stored with b->setMatrix()
2) Avoid calling element->isIdentity() for the whole transform stack
(can be expensive is element is a matrix)
3) Make the key frame interpolator use binary search instead of a
linear one. This is very noticeable in scenes where some geometry has
long repeating animations that start at the same time, you will see
the update time grow then reset and grow again."

The osg 3ds plugin modify the exported materials name in the same way it modifies the node names.
I've added an option to preserve originals materials names, with the assurance of unique material names are preserved."
