tab-completion crash

tab-completion crash

[David Gómez]

Hi all,

Latest zsh CVS gives me this crash (with the old
completion, i'm not using zstyle at all):

% [<Tab>

That is, typing a square bracket and hitting Tab make
zsh crash. If you're not able to reproduce this i can
compile zsh with debug info to generate a backtrace.

cheers,

Thanks, that's a bug I introduced in math context (which it isn't
really, but compctl is thick) when trying to get the words working with
multibyte characters.
