I just experienced a crash in a (unpatched) 21.2.5 (Linux 2.0.35, egcs1.1, --gung-ho) it had been running happily for quite a while (like, a couple of days, core dump size was 21MB). The crash happend in Gnus, when displaying a new article (apparently while trying to bring up the picon). I'm afraid the core is not very helpful, as I don't have the executable and that source-tree around anymore... :-( Fatal error: assertion failed, file /local/srcdisk/gunnar/src/XEmacs/xemacs-20/src/lisp.h, line 1154, RECORD_TYPEP (obj, lrecord_vector) || MARKED_RECORD_P (obj) Fatal error (6).
