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
No idea what crashes blender. Just press play and wait some seconds.
Exact steps for others to reproduce the error
I would love to help solving this issue, so when someone could remind me where the crashreport usually lands in Linux, i could share that as well.

@user1 you can run Blender from console with
-d
argument, this should leave path to .crash.txt file. Console output and crash file will be appreciated. Also see https://docs.blender.org/manual/en/latest/troubleshooting/crash.htmlI can't reproduce crash on Windows.

@lichtwerk can you reproduce?

It's a use after free inside line-art. Seems that the Object's evaluated Mesh datablock was deleted as part of depsgraph processing:

@ChengduLittleA Could you take a look?
Narrator1.crash.txt
This is really weird. It's supposed to be a bug that's fixed with the same line on D14040. The animation plays slow here but I did not get any crashes after repeated trying. Although I seem to get quite slow in the first few or tens of frames and later it's like one sec per frame.
Probably need a depsgraph guy to see if my usage of dg is wrong...

For some reason, I am not able to reproduce this anymore (not even in 3.2), can anyone else still repro the crash?
I think this was fixed at some point without closing this ticket.
The report is from the alpha version of 3.2, so I guess this was fixed in the 3.2 point release.
@lichtwerk I think we can close this if you can't reproduce it anymore.
OK, will close then.
If issues should creep up again, please open a new report for this then.
