Worked: N/A

Short description of error
I'm experiencing consistent crashes when redoing rapidly, i.e. when holding down Command + Shift + Z. This is on macOS 10.15.5 with Blender 2.83. Attached is the crash log from the most recent crash. It might be worth mentioning that I've increased the undo buffer size in the preferences from the default of 32 actions to 128 actions.blender_2_83_redo_crash.txt

Exact steps for others to reproduce the error

Apparently the crash is indeed in ED_info_stats_string:

Can you try the latest development snapshot of blender (2.90)? https://builder.blender.org/download

I'm still seeing an occasional crash during redo with the development snapshot (version: 2.90.0 Alpha, branch: master, commit date: 2020-06-22 22:06, hash: 51bf04383a, type: Release), but the call stack is different. The crash still occurs within header_draw however. Attached is the crash log and system info.blender_2_90_redo_crash.txt

The crash log of this system is somewhat unpredictable.
Perhaps it is related to the same problem described in #77867

But it's hard to say.

Since nobody is really reproducing this and since there have been many fixes around UNDO, I would kindly ask @aleksijuvani to reconfirm that this is still an issue even in fresh builds from https://builder.blender.org/download/?
