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.
