No, but I can't think of much more data I could ask for to help narrow this down. >I've been plagued with a problem running XEmacs.

No dump, no nothing. I have a vague idea what could be causing this and ran some tests yesterday to no avail, of course. Corinna is also running tests. I suspect that somehow a pid is being reused, which means that somehow a handle is being closed which shouldn't be closed. I'm going to add more debugging to cygwin and generate a snapshot with the debugging turned on. I'll post a notice about the snapshot when that happens, so please give it a try. If there are problems there should be an error message which will provide clues about what is going on. cgf -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
