Short description of error
The linked blend file suddenly started crashing immediately after loading in ~90% of my attempts.
Very reminiscent of a bug I reported in December , which had been resolved. And again, the data transfer(custom normals) may be involved.

Exact steps for others to reproduce the error

load blend file 10 times, it should crash almost always
there may be better chances it loads, when loading without UI (and from solid shading), I'm not sure

@MACHIN3 it is ok to upload big files. (It is not uncommon that people upload >600MB "minimal" .blend files here :P)

Anyways,

I'm getting this assert when loading the file:

BMESH_ASSERT failed: blender/source/blender/bmesh/intern/bmesh_core.c, bmesh_elem_check(), 735 at 'err == 0'

The error is: IS_FACE_NULL_VERT
So this means that there is a loop that doesn't have a vertex in it.

@mont29 any ideas?

Error happens in validation of BMesh in Bevel code, so I guess that’s for @howardt to investigate.

This happens at the very beginning of the bevel modifier's applyModifier function, before bevel actually does anything, when it is trying to do BKE_mesh_to_bmesh_ex() to convert the input into a BMesh. So I don't think this has anything to do with Bevel, but rather some kind of corruption in the input file or something gone wrong in the generic mesh to bmesh conversion procedure. I can look into this further but not right away. Is there someone better than me to look at this?

p.s., I realize that the stack trace in the intial report is during the heart of bevel. My crash happens much earlier, as the previous note said. Perhaps because it is a Debug build? My stack trace:

Erf, finally took some time to look at that one, issue here is that the mesh (maybe several, but at least one, Cylinder.031) is invalid. One can easily check that by appending the mesh itself (not its object), and then running bpy.data.meshes["Cylinder.031"].validate(verbose=True) from the py console, and checking the error messages in the regular system console:

ERROR (bke.mesh): /home/i74700deb64/blender/__work__/src/source/blender/blenkernel/intern/mesh_validate.c:589 BKE_mesh_validate_arrays: 	Loop 14 has invalid vert reference (8192)

So unless @MACHIN3 can provide us a way to reproduce such corruption in the mesh, am afraid we cannot do anything here.
