completion killing zsh

[Timothy J Luoma <tjlists@xxxxxxxxxxx>]

Don't ask me why, but when I try this completion (ie: I hit 'tab' after  
'ivvvv' below) zsh dies:

(zsh = 3.1.5-pws-20)



(gdb) run
Starting program: /usr/bin/zsh
# appnmail -ivvvv Program generated(1): Memory access exception on address  
0x2f (protection failure).
0x36d45 in ?? ()
(gdb)

here's the completion:

compctl -K allmbox  'S[-]' -- compactmail appnmail


here's the reply function "allmbox" :

allmbox ()
   {
   if [[ $mboxs = "" ]]
   then
   	mboxs=(`find ~/Mailboxes/ -type d -name '*.mbox' -print`);
   fi
   reply=$mboxs;
   }


what am I doing wrong here?

is it a buffer overflow maybe?

# find ~/Mailboxes/ -type d -name '*.mbox' -print|wc
