Delete Branch "%!s()"
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?

Short description of error
When trying to render the animation in the given project, it either crashes Blender or causes it to hang indefinitely.
Exact steps for others to reproduce the error
Recording of me rendering the project and making Blender crash.
Hi, thanks for the report. Unable to confirm the crash in 3.6
Does this happen when you start blender from command line with -t 1 argument?
Yes, I can reproduce it with
-t 1
, I've attached the crash log with it set:I explored a similar bug. Some kind of modifier, or something else, multithreadedly takes some single data for writing. A result of 10 copies, this is an attempt to delete itself 10 times.
But the scene file does not contain geometry nodes, so this is something new. If it has the same reproducing time range as #109583, then it's may a duplicate. But need to be sure that this is also related to normals. Otherwise, it can be considered a separate type of bug.
Thanks. This has now generated the call stack (and
EXCEPTION_INT_DIVIDE_BY_ZERO
exception).From recent logs. it seems crash triggers while freeing the memory.
Maybe irrelevant but could you check whether it crashes with
--debug-depsgraph-no-threads
argument?I can't reproduce it either. In addition, it is better to remove the script.
I've tried again with
blender --debug-depsgraph-no-threads <THE_FILE>
and it also produced the crash with the same traceback.I then tried rendering with all scripts disabled, this time the crash does not occur and it renders all frames completely fine. I toggled each script and found that disabling the addon "Animation: Wiggle 2" from https://github.com/shteeve3d/blender-wiggle-2 stops the crash.
In one of the runs with "Wiggle 2" and
--debug-depsgraph-no-threads
enabled, this was printed in the console after crashing:I've only been able to cause that error once, all other runs just give the same
EXCEPTION_INT_DIVIDE_BY_ZERO
exception.Occasionally, instead of crashing, Blender freezes indefinitely instead with this error:
The crash log file
render crash.crash.txt
is actually empty in this case, it seems Blender never actually writes to that file.In this case, you'd better report the bug to the addon author. We can't fix the problem if it's not in blender, but in a script.
