Subject: 23.1.50; Core dump
Date: Wed,  3 Mar 2010 09:37:06 -0800 (PST)

I was running Emacs over an NX Client session (essentially a compressed X11.app connecion) and when I came back the next morning, it had core dumped.

Thank you for your report.

We would need a backtrace from a non-optimized build, to be able to
make sense of this crash.

Btw, you are using quite an old development version, more than 8
months old.  Could you perhaps try running the latest one, or the
pretest available from alpha.gnu.org?

More information was requested more than a year ago, but was apparently
not given, so I'm closing this report.  If this is still a problem,
please reopen the report.
