From: Vincent Lefevre <vincent@vinc17.net> To: zsh-workers@zsh.org Subject: Ctrl-\ while executing a pipeline made zsh quit Date: Tue, 26 Apr 2022 02:36:49 +0200 [thread overview] Message-ID: <20220426003649.GA100943@zira.vinc17.org> (raw) With zsh 5.8.1 under Linux (zsh 5.8.1-1 Debian/unstable package), while I was executing a pipeline, I typed Ctrl-\ to interrupt it (Ctrl-C had no effect), which made unexpectedly zsh quit: SIGQUIT should interrupt the commands zsh starts, not the interactive shell itself. The backtrace: Core was generated by `zsh'. Program terminated with signal SIGQUIT, Quit. #0 0x00007f6e9cd2dbe8 in __GI___sigsuspend (set=set@entry=0x7ffc0653d8e0) at ../sysdeps/unix/sysv/linux/sigsuspend.c:26 26 ../sysdeps/unix/sysv/linux/sigsuspend.c: No such file or directory.
