Gnus v5.8.4 XEmacs 21.2 (beta26) "Millenium" [Lucid] (i686-pc-linux) of Mon Jan 17 2000 on trinity 200 Leafnode NNTP Daemon, version 1.9.7 running at 10.10.10.10 I have found a piece of mail that crashes the above combination every time. The crash is so bad that xemacs quits as well. I'm submitting this as a bug for gnus, because from the look of the backtrace it has something to do with gnus running the article through w3. If you feel this is an bug with xemacs, let me know and I send it there.
