Seg fault with zmodload -u

[Oliver Kiddle <opk@xxxxxxxxxxxxx>]

zsh -f
zmodload -ud zsh/zleparameter zsh/zle
zsh: 18383 segmentation fault  zsh -f

I found this because I was going through the various zmodload options 
because I was doing an _arguments based completion for it. It happens
wherever the dependencies are defined, i.e, zmodload -d foo bar;zmodload
-du foo bar will also result in a seg fault.

This is on 3.1.9-dev-4 plus patches up to 12568 on AIX. If it isn't
reproducible elsewhere, I'll upgrade to the latest cvs and try again.

On the subject of zmodload completion, how would I prevent the 'module
alias' description from being displayed when there are no module
aliases - do I have to put the zmodload -A output in an array first and
then not call the _requested line if the array is empty - or is there a
better way?
