This is enough to reproduce the crash for me:
% zsh -f
localhost% PS1=%~
~autoload -U compinit
~compinit -D
~zsh_directory_name() { }
~<press C-x?>
_complete_debug:9: failed to close file descriptor 3: bad file descriptor
zsh:1: failed to close file descriptor 3: bad file descriptor
zsh: segmentation fault  zsh -f

With this patch, the crash is no longer happens here.
