I reproduce using the binary on Linux, but not in my local build. Investigation needed.

[mwestphal]

I reproduce with ANY .usdz. .usd does not have this issue.

The file Table.usdz outputs this warning when opening with --verbose:

Found material bindings on prim at path (/scene/Meshes/Sketchfab_model/root/GLTF_SceneRootNode/Cube_0/Object_4/Object_0) but MaterialBindingAPI is not applied on the prim

When opening it AFTER Longsword.usdz, it crashes in:

....

Looking at the code, it seems like it crashes exactly where the warning is emitted.
See https://github.com/PixarAnimationStudios/OpenUSD/blob/9b0c13b2efa6233c8a4a4af411833628c5435bde/pxr/usd/usdShade/materialBindingAPI.cpp#L669

Longsword.usdz has a similar warning too

I tried chaining several usdz files without this warning, and it works just fine.
