[Pkg-zsh-devel] Bug#886884: zsh sometimes crashes when it receives a SIGQUIT signal

[Vincent Lefevre]

Package: zsh
Version: 5.8-5
Followup-For: Bug #886884

I've just reported the following issue in zsh-workers:

Ctrl-\ during completion makes zsh quit. To reproduce the problem
with "zsh -f" under Debian/unstable:

Run the following commands:

zstyle ':completion:*' menu select=long
autoload -U compinit
compinit

Then ';' followed by [Tab]. I get:

zsh: do you wish to see all 6124 possibilities (3062 lines)?

Type [Tab] again, then Ctrl-\. I get:

[...]
_gem                                lnstat
_generic  ^\zsh: quit (core dumped)  zsh -f

(with a backtrace).

This is the same kind of issue.
