and the precise symptoms of the bug:

I created diff/patch file (using the cvs diff) and reversed the diff afterwards, but when I opened the unapplied diff and did <enter> on the line to be added, it crashed (Segmentation fault)

Please a recipe for reproducing this bug, including if possible the file
that caused the crash.

Also, Emacs 21.4 is rather old; I would suggest trying a more recent
version of Emacs, as there's a good chance this bug has already been
fixed.  Could you try that, and report back?

This report is being closed because it refers to what is now an old
release of Emacs and there is no information for us to be able to
reproduce the problem. If you still see the issue with the latest
release, 23.3, please reply and we can reopen the report if needed.
