From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.1) Gecko/20021003 Description of problem: Emacs core dumps every few days. The crashes are "random", i.e. I can not correlate them to what I was doing. Today it crashed on Alt-x man <enter> topic <enter>, the other time on resizing a window, the other time on opening a file, etc. I usually use the same emacs session for a day, and often there are dozens of buffers and a few frames simultaneously. But I observed crashes with a single frame (like today) and only a few buffers. It never happened with pre-21 emacs, all the trouble began after an upgrade to RH8.0. Version-Release number of selected component (if applicable): emacs-21.2-18 How reproducible: Sometimes Steps to Reproduce: 1. Use a single emacs session with multiple buffers for a while. It does not always crash, though. Additional info: I'll attach a core dump and my .emacs file.

The core dump can be found at http://e614db.triumf.ca/~andr/emacs-bug/ (bugzilla said it was too big for an attachment...)
There is one more core dump from today's crash (core.28111) on the web. http://e614db.triumf.ca/~andr/emacs-bug/ This time it crashed when I clicked "Buffers" on the menu bar.

What does the gdb backtrace of the first coredump look like? It would be good if you could try the latest emacs package in rawhide, to see if the problem still persists for you. Since the lib in rawhide are probably newer than in 8.0, you'll probably have to rebuild the package yourself on 8.0, unless you want to install rawhide in a testbox and try that.
Closing for now. Please reopen if it is still happening with Emacs 21.3 in rawhide.
