Subject: coredump completing scp
From: Vin Shelton <acs@alumni.princeton.edu>
To: zsh-workers@zsh.org
Content-Type: text/plain; charset=ISO-8859-1

With a recent CVS build (ZSH_PATCHLEVEL is 1.5190), here's a recipe
for an abort:

zsh -f
autoload -U compinit
compinit -u
scp <TAB>

This shell was configured --with-zsh-mem and that seems to be required
to provoke the coredump.

Here is the backtrace:

Core was generated by `/home/acs/tst/bin/zsh -f'.
Program terminated with signal 6, Aborted.
