Subject: PATCH: trap handling segfault
Date: Fri, 9 Jun 2000 10:38:35 -0400 [thread overview]
Message-ID: <20000609103835.A22587@scowler.net> (raw)
In-Reply-To: <20000609100241.B21890@scowler.net>; from schizo@debian.org on Fri, Jun 09, 2000 at 10:02:41AM -0400
This patch doesn't crash the snippet I posted, and it prints
BYE after the script in 11735. I'm going to commit this under the
assumption that someone with a better understanding will reverse it
if there are horrible side effects.
