Delete Branch "%!s(<nil>)"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
System Information
Operating system: Darwin-20.2.0-x86_64-i386-64bit 64 Bits
Graphics card: AMD Radeon Pro 5500M OpenGL Engine ATI Technologies Inc. 4.1 ATI-4.2.13
Blender Version
Broken: version: 2.92.0 Alpha, branch: master, commit date: 2021-01-01 18:07, hash:

Short description of error
When I change the size of a just added object, Blender will crash within a few seconds.
Exact steps for others to reproduce the error
Start new file
Delete everything from scene
Shift A, add object (tested with plane, cube, uv sphere and torus)
From the popup menu, use the mouse to slowly adjust the size or radius
If you keep doing this, within a few seconds Blender will crash.
Crash log:
Crash resizing object.txt
Added subscriber: @blenderrocket
Added subscriber: @rjg
Changed status from 'Needs Triage' to: 'Needs User Info'
I couldn't reproduce the problem. Could you please check if enabling Undo Legacy avoids the crash?
In the Experimental tab enable Undo Legacy
If this avoids the crash it is likely the same problem as #80203.
Yes that avoids the crash.
@blenderrocket Could you please disable Undo Legacy, save the preferences and then try to start Blender from the terminal with the following command (path to Blender might need to be adjusted):
Please try if you can still make Blender crash. If it still crashes, please upload the resulting crash report and the log file
blender_debug_output.txt.Here you go:
blender_debug_output.txt
And a crash report:
Crash resizing object2.txt
Also when running with this command, one of the times I tried Blender just locked up without a crash with the Mac spinning cursor, then I had to kill it manually.
Just to make sure that your not having an additional issue unrelated to the undo/depsgraph problem, could you please do one more test with the most recent daily build of Blender 2.92 .
Same with 2.92.0 Alpha, branch: master, commit date: 2021-01-03 01:04, hash:
1e8f266591Does it also give the same stack trace or a different one (in the
.crash.txt)?No idea what to look for, but please see for yourself:
Crash resizing object3.txt
Closed as duplicate of #80203
Thank you for your help. This does appear to be the same issue.
