System Information
Operating system: Linux-4.15.0-55-generic-x86_64-with-debian-stretch-sid 64 Bits
Graphics card: GeForce GTX 750 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 384.130

Blender Version
Broken: version: 2.81 (sub 4), branch: master, commit date: 2019-09-02 15:37, hash: 283d96de11
Worked: 2.80 official

Short description of error
Interaction with a particular object - such as entering/exiting edit mode or adjusting modifiers (or eventually after rendering/baking an arbitrary number of times) - causes Blender to crash.

Exact steps for others to reproduce the error
Download the attached .blend file and open it.
The object concerned is named Circle. It is a long thin cylinder with a spiral effect made using modifiers. It is already selected.

objectInteractCrash.blend

Cause a crash by doing one of the following:

  • Transform the object (G/R/S). Should crash immediately.
  • Enter edit mode (tab). Should crash immediately, or on exit edit mode.
  • Adjust any modifiers properties or visibility. Should crash immediately.
  • Toggle "Disable in Viewports" off and on in outliner. Should crash after toggling back on.
  • Render (F12). Each render should take about a second. It should crash after about 4 renders.
  • Shift-select the object BakeTarget and bake. As with render, it should crash after about 4 bakes.

Extra Info
The object was made inside Blender (hard to say exactly when, but definitely late-june to mid-august) in master branch builds. It can be interacted with without any apparent issues in official 2.80 build.

Terminal output in case of crash on enter edit mode:

Read blend: /home/thomas/Documents/Blender/objectInteractCrash.blend
Writing: /tmp/objectInteractCrash.crash.txt
Segmentation fault

(If it doesn't crash immediately, you'll have a couple of "couldn't unmap memory" messages.)

The number of "couldn't unmap memory" messages generally correspond to the number of renders (though sometimes not?) On one occasion Blender hanged on the render rather than crashing.

I've narrowed the problem down to the Vertex Weight Proximity modifier. In particular the cause seems to be having Proximity Mode set to Geometry, and Proximity Geometry set to include Edges.

Attached is a very simple scene to demonstrate:

objectInteractCrash2.blend

Move either object and Blender should crash. Deselect edges in Cube's Vertex Weight Proximity modifier, and it should not crash.

If you run from terminal, you can see that sometimes Blender closes with a segfault, and sometimes with:

Couldn't unmap memory
blender: tpp.c:84: __pthread_tpp_change_priority: Assertion `new_prio == -1 || (new_prio >= fifo_min_prio && new_prio <= fifo_max_prio)' failed.
Aborted
