iplStaticMeshCreate crash on IPL_SCENETYPE_DEFAULT but not IPL_SCENETYPE_EMBREE, testcase provided

When adding specific static meshes on scenes that are of type IPL_SCENETYPE_DEFAULT it leads to an access violation on iplStaticMeshCreate

The current workaround is to use IPL_SCENETYPE_EMBREE to prevent this from happening. Below I've provided a test binary built in debug mode with an attached pdb https://github.com/ogniK5377/steamaudio-issue-repro/releases/tag/StaticMeshCrash The source for the following test case is provided here too https://github.com/ogniK5377/steamaudio-issue-repro/blob/main/src/StaticMeshCrash/main.cpp

The scene is provided as well as a command line option to only provide a limited subset of triangles up to the crashing triangle of the static mesh

Edit: Looks as if I can reproduce it as well if there are 130 overlapping triangles
