Access violation - code c0000005 (first/second chance not available)
Is generally an issue with a pointer being accessed that is NULL. Seems there is a bug within the importer. The pointer is not checked for being NULL and processed.
fbxskeletalmeshimport.cpp Zeile 626
Blender FBX is not the best implementation. As far as I know it has not been updated for a while.
Make sure when exporting from Blender to select Version: FBX 6.1 ASCII, at least it caused less issues for me.
The pointer access should be checked though and needs a fix, escpecially as it is a recursive function that relies uppon that pointer.
