System Information
Operating system:
"Ubuntu 20.04.5 LTS" XFCE window manager
32 GB RAM

Graphics card:
NVidia GTX1080 (Zotac Mini) -- Driver Version: 390.157

Blender Version
Broken: 3.4.1
Worked: 3.5

Short description of error
Forcing change to rigid body physics simulation by grabbing passive rigid body object (conveyor belt ) and then canceling results in segmentation fault on play of animation.

Exact steps for others to reproduce the error

  • Open attached Blend file
  • In 3D viewport, select belt mesh
  • NEW MISSED STEP Play Animation without touching anything (note crazy physics)
  • g, drag, escape the "Belt" object to force physics cache to update.

Play animation. Segmentation fault should occur.

Hi Richard, Thanks for taking a look at this. Please note the edit to the reproduce steps.

Also, I'm new to debugging Blender. The crash file was basically empty convetor.belt09.crash.txt

so I tried with
blender -d
But, same result. I see a whole slew of debug options. Can you suggest some?

If not, no worries, I'll do some more reading.

Starting Blender with:

blender --debug-all --debug-value 99 --debug-python

and reproducing the crash. File now contains convetor.belt09.crash.txt

Also note earlier edit where I could not duplicate in 3.5.0 alpha.

Can duplicate pretty consistently in 3.4.1

This may be more useful. Command line capture to file:

blender --debug-all --debug-value 99 --debug-python > blender_stderr_stdout.txt 2>&1
blender_stderr_stdout.txt

Thanks for updating steps, unfortunately I am still not able to reproduce the issue. Could be linux related though. @lichtwerk, can you check?

Just to rule out the video card/drivers I tested on an older Linux PC using two versions of Blender.

Results:

$ lspci | grep VGA
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Juniper XT [Radeon HD 6770]

$ grep PRETTY /etc/os-release 
PRETTY_NAME="Ubuntu 18.04.6 LTS"

$ ls /data/bin/blender-3.* -d
/data/bin/blender-3.1.0-linux-x64        # Cannot duplicate
/data/bin/blender-3.4.1-linux-x64        # Can duplicate -- same version as initially reported

Hi, I can confirm on Windows. Crash seems to be fixed after 3.4 release. I'll find the exact commit shortly.

@PratikPB2123 : did you ever find a commit to backport for 3.3 LTS?
