From a fresh blend,
Create a plane
Add a GeoNode modifier
Append that Geo Node ("Spring") from the attached blend
Select "Spring" on the plane
Delete one edge from the plane

When I try tab after loading tab-segf.blend, I get something like the first stack in Evan's message. Somehow, in draw_subdiv_cache_extra_coarse_face_data_mapped, the bmesh has zero faces yet the mesh argument has many. I don't have time right now to dig into why.

This issue was referenced by 90999a0694

Changed status from 'Needs Triage' to: 'Resolved'

I'm getting the segfault on the new_polys line still. (Blend attached)

466         new_polys[i] = new_poly(new_loop_range[ i * 4 ], 4);

I also can't append the collections into a fresh blend (same error).
