Short description of error

Exact steps for others to reproduce the error
I was following this tutorial:
https://cgmasters.net/free-tutorials/modeling-exercise-microphone/
around 13m20s, when creating the bezier curve, i discover i did something wrong (that tutorial uses blender v2.71), so i did some undos (about 6-7 undos) to rectify. suddenly after pressing a ctrl+z, blender crashed with a segmentation fault.
i tried to reproduce it to no avail, but the backtrace provides some info.

i see there're many open bugs related to crashes after UNDO. hopefully this is a different bug.

Event Timeline

I had a similar instance occur on MacOS. Segmentation faults seem to occur every ~10 minutes, sometimes with no obvious cause/action.

Keating Reid (BigfootLives) claimed this task.

Seems to have been fixed in the latest builds.

Yesterday it happened the same on my Windows 10 (64-bit beta from 29th of May), and while working on a scene, i pressed ctrl+z and blender crashed (process got killed. no errors, no core file, nothing).
So, not sure if it's the same thing you mention it's fixed, but a 'Undo' can crash yesterday's beta.

Brecht Van Lommel (brecht) triaged this task as Needs Information from User priority.

There are indeed multiple reports about undo open, and this may be a known case.

But we really need exact steps to reproduce the bug, otherwise we can't investigate. If they are hard to find, we better assume it's one of the known cases.

Closing due to lack of information to investigate further, we can reopen the report if more information is provided.

Today I downloaded last beta (blender-2.80-f990c23bcfb5-win64). I was modelling a basic shape and after a few Undo (ctrl+z), it crashed. Please find attached console log.

Thanks for the log, but we need a .blend and exact steps to redo the problem, the log is not enough.
