From: newsham AT aloha DOT net (Tim Newsham) Subject: crash dumps 23 Oct 1997 16:31:16 -0700 Message-ID: <199710232100.LAA24279.cygnus.gnu-win32@haleakala.aloha.net> Mime-Version: 1.0 Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: 7bit To: gnu-win32 AT cygnus DOT com Hi, Having the exceptions (and stack trace) dumped to stderr is usually of little use to me (especially when lots of programs are running at once in the background), so I patched cygwin.dll to dump the stack trace to the more traditional file .core. This way I can look around the filesystem for .core files to see if things crashed while I wasn't paying attention or had stderr redirected someplace else. I think this is the sensible way to handle this and would like it if cygwin adopted this technique :) The patch is included below. You may do what you want with it, I release any rights to the code.
