Re: trap DEBUG + set -o DEBUG_BEFORE_CMD not setting $? nonzero in current CVS

["Rocky Bernstein" <rocky.bernstein@gmail.com>]

I didn't have a problem writing a program that when run gives exit
code 0 if this bug is fixed and exit code 10 if not.

I tried from checked out sources from a couple days ago when there was
a bug versus currently patched sources. It probably shouldn't be too
hard to work this into the testing system.


#!/usr/local/bin/zsh -f
cmd='./fdasfsdafd'
[[ -x $cmd ]] && rm $cmd
set -o DEBUG_BEFORE_CMD
trap '[[ $? -ne 0 ]] && exit 0' DEBUG
$cmd  # invalid command
# Failure
exit 10

# Put the above in a file, call it and test the exit code.
