The mesh is heavily corrupted, you can see this from console log when running
for mesh in bpy.data.meshes: mesh.validate(verbose=True)
.The real fix would be to to fix the tool which produced that corrupted mesh, but for that we need to know how to reproduce such a corruption.
The mesh was generated using a cloth simulation with a previous beta version of Blender 2.8. I was able to render without any problems on said version. Not sure why it's it corrupted now, but I don't expect Blender to hard crash either ?.

Changed status from 'Open' to: 'Archived'
@arcnor Blender does not expect corrupted meshes, guarding against those would be terribly costly on performances and workload levels. Archiving until we get a reproducible case to replicate such corrupted mesh generation.
