Robert Osfield 8df1106957 Fixed Coverity reported issue. 
CID 11388: Resource leak in object (CTOR_DTOR_LEAK)
Allocating memory by calling "new char[numBytes]".
Assigning: "this->_startPtr" = "new char[numBytes]".
The constructor allocates field "_startPtr" of "struct DataConverter" but there is no destructor.
Assigning: "this->_currentPtr" = "new char[numBytes]".
The constructor allocates field "_currentPtr" of "struct DataConverter" but there is no destructor.
