Crash when loading glb model files via addStyleModel about mapbox-maps-ios HOT 5 OPEN

Ok, just detected the problem. Your model shares indices between meshes Cube.10 and Cube.11 and when releasing them in the draco compression path it was causing a double free. Fix implemented, and will reach the next release hopefully. For the time being, either you can avoid to use draco compression or use different indices array for each primitive.

Thanks a lot for the report and the data!

I will close this issue once the fix is released.

Thank you so much @jtorresfabra!

Hi @MichaelDanielTom:
Thanks for the headsup. Is this happening with a model in particular that you can share? Or is it happening for you with every model? Mapbox landmarks use glb format as well, and we did not detect any problem with those, so wondering if your models have any particularity that we could have missed.

@jtorresfabra Upon further inspection, it looks like most of the glb models are working as expected (my bad for first assuming it was a problem with all glbs), and the crash is happening with this model in particular. Not entirely sure what's different between this model and the others that are working but hopefully it's helpful!

@jtorresfabra It looks like with that model, if I export that model to glb from Blender with the Compression setting checked, mapbox will crash, but exporting the same model without compression checked will work ok. Here are the settings in the Blender gltf export extension that will crash mapbox (unchecking compression makes it work with mapbox).

Looking back at the crash I see a KHR_draco_mesh_compression in there too.
