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
The backtrace:
Core was generated by `zsh -f'.
Program terminated with signal SIGQUIT, Quit.

BTW, in addition to the SIGQUIT issue, it shouldn't be that easy to
generate so much output for the completions (I did that by mistake).
