Issue with glb2 export

I'm experimenting with glb2 export for scenes with skeletal animations. I did try to import and re-export a sample file that I found in khronos's examples and it worked like a charm. However, when I work in a more complicated mesh of mine, my app simply closes without any warning or even the known "Access Violation exception". I've been experimenting and I think I have traced that the issue is related with the existence of bones in the mesh. When I remove all of the bones, export works. Even with a single bone with no vertex weights it still crashes. FYI, the same assimp.scene exports successfully when using fbx, or collada.

No source file or test is named. Start by reproducing glb2 export with the reported skeletal mesh, then compare behavior with bones removed and with FBX or Collada export; done means the application no longer closes and the scene exports successfully.
