I experienced the same problem by XEmacs of the versions before and after releasing 21.4.16. It makes it hard to test Gnus and some ELisp packages with it. > When I kill the xemacs process (after say 5 minutes of burning cpu on > a P4 2.4 GHz), I always get a backtrace that starts with: > Lisp backtrace follows: > string-match("=3D\\?\\([^][- ()<>@,;:*\\\"/?.=3D]+\\)\\(?:\\*[^?]+\\)?= \\?\\(B\\|Q\\)\\?\\([!->@-~ ]*\\)\\?=3D" "=3D?iso-8859-1?Q?Sj=3DF8gren?=3D") > # bind (word) > rfc2047-parse-and-decode("=3D?iso-8859-1?Q?Sj=3DF8gren?=3D") > # (unwind-protect ...) > (The actual string is different, sometimes it is the From:, other > times it is the Subject: - it has, so far, always been encoded). > It doesn't happen every time I enter the same group/read the same > article, only sometimes. Which is, of course, rather troubling. I'm not sure whether it is related to neither the regexp matching nor the rfc2047 decoder. I recommend you to go to the xemacs-beta list if you still want to continue using XEmacs. I lost interest to that long ago. Sorry.
