Do you have a concrete reproduction case that can cause this crash? This particular panic is hard to reproduce.

If you were using window splits, this may be fixed by #4733

I do not have a concrete reproduction case that can cause this crash. Honestly I'm not sure if it is even because I clicked undo. Helix has crashed similar to this many times, not only when I didn't know what I clicked, but mostly when I started using Helix a month or two ago, so I reported this because it is now a rare event.

Can I ask, while we're here, is Helix supposed to forget your registers when you close the program? I don't want to type my macros again every time.

I must say, thank you for making this editor, it is fun to follow the project. I really don't mind the lack of plugins and sessions (and saving registers), that simplicity makes it nice. And the selection mode is just what I missed.

Another unrelated thing while we're here: In the beginning, I was quite happy about the keybind menus, but I wanted a menu in the beginning that said which keys open keybind menus, i.e. :, [, g, space. I had FOMO about there being a menu I didn't know about.

I was using vertical window split, but I don't know if it is related.

Thanks again. Just go ahead and close the issue.

Since you had a split I think this is #4732. I'll close in favor of that.

Persisting state like registers is covered in #401
