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: win 10
Graphics card: GTX 1070
Blender Version
Broken: (2.9.0 Alpha daily build)
Worked: (2.8.3)
Running a simple modal script where I am creating a new object and then cutting a new undo check point with bpy.ops.ed.undo_push()
It crashes when UNDO limit is reached
Exact steps for others to reproduce the error
4 Crash..
Same problem if instead of bpy.ops.ed.undo_push() you return FINISHED from the modal op and add bl_options = {'REGISTER', 'UNDO'} to the op definition
So, this bug appears to be related to the undo system
Also, worth mentioning that running with 'blender -d' does not crash!!

I had a similar crash drawing in grease pencil. Just open 2D template and start to draw...at some point you will get a crash. This is the crash log:

Thanks for the report. I'm guessing this is the same issue as #77396.
This should be fixed with
67b17684e6
, which will be in the next daily build.I'm going to close this as resolved, but please comment here if there's still an issue with the next build!

Nevermind, my bad, just saw the comment from Antonio.
@HooglyBoogly I compiled the code five minutes ago, so not sure that commit fix the bug.

@antoniov your backtrace looks terribly similar to the issue fixed in 67b17684e6...
In any case, I cannot reproduce with current master (neither debug build with ASAN, nor release one), so am going to ask for a confirmation first here. :)
@mont29 thanks. I can't reproduce this one either with the latest build. I have another thus, related to undoing and object linking to the scene. But i think is better to open another task for that one if I can reproduce it..
Changed status from 'Needs User Info' to: 'Resolved'
Indeed, lets keep an issue per task. ;)
Thanks, closing then.
new issue probably related #77557
