I have no idea how to use "valgrind".

zsh -f
autoload -U compinit; compinit -C
zstyle ':completion:*' matcher-list 'm:[-._]=[-._] r:|[-./_]=**'
mkdir bug; cd bug
_f<TAB>
zsh: 2588 segmentation fault  zsh -f

The linux zsh produces no coredump but fortunately the Cygwin does
(although I have disabled it via "ulimit -Sc 0")
