And you press <Shift-Tab> again.
Terminal emulator suddenly quits

According to my investigation, this problem seems to occur from the commit of fbd093f7c97a64da92020ba5a6c2756ff56e1c9d.

I'm also seeing this issue. It seems to be a crash in zsh.

Fixed.

Thank you for the update. But, I've tried the main branch and it still seems to reproduce.

Same here, the issue still reproduces. Here's a stack trace: https://pastebin.com/TgK4Ajd0

OK, yes, I can reproduce it, too. Let me have another look.

Looks like a bug in Zsh to me: https://www.zsh.org/mla/workers/2021/msg01162.html

[yutkat]

Oh! it's a bug in zsh. I'm surprised. Indeed, the following steps reproduced the problem in my environment.

Steps to reproduce:

zmodload zsh/complist
tst() { compadd bar baz; compstate[insert]=1 }
zle -C tst menu-select tst
bindkey '^I' tst
bindkey -M menuselect '^[[Z' reverse-menu-complete
ba^I^[[Z

But why doesn't it reproduce with fbd093f commit? I want you to revert this commit if possible.

[marlonrichert]

Don't worry, I already know how to work around this. I will commit a fix later today. 🙂

[marlonrichert]

All right, now it should really be fixed. 🙂

[yutkat]

Great work :tada: It works for me. Thank you, marlonrichert.
