This problem occurs on both zsh 3.0.2 (on Linux) and zsh 3.1.0 (on Solaris).

Run zsh -f and source a file containing the following:

    friends=( duvall )

    _machines=( lorien.princeton.edu cassius.mts.jhu.edu )

    function _get_hosts {
      typeset -l _user
      reply=()
      read -l
      _user=($=REPLY)
      reply=($_machines)
    }

    compctl -q -k friends -S @ -x 'n[0,@]' -K _get_hosts -- finger talk ytalk

Now type:

    % finger duvall@lo<TAB>

Which expands to

    % finger duvall@lorien.princeton.edu _

Now erase back to the @:

    % finger duvall@_

and expand:

    % <lots of garbage>

After this, it seems zsh is pretty screwed up.  I've managed to get both
bus errors and segmentation faults.  Sometimes it happens when hitting
control-C, sometimes it doesn't happen for a while.

Anyway, I can regularly reproduce this.  Anyone else seen this?  I can
recompile and get a stack trace if that would be of any help.

Thanks,
Danek
