This bug report will be sent to the XEmacs Development Team, not to your local site managers!! Please write in English, because the XEmacs maintainers do not have translators to read other languages for them. In XEmacs 21.2 (beta46) "Urania" [Lucid] (i686-pc-linux, Mule) of Thu Apr 12 2001 on dahaIM.dyndns.org configured using `configure --prefix=/usr/local/xemacs --with-athena=next --with-menubars=lucid --with-scrollbars=athena --with-dialogs=athena --with-widgets=athena --with-sound=esd --with-mule --error-checking=none' Please describe exactly what actions triggered the bug and the precise symptoms of the bug: When I open (say) a larger lisp file with font-lock turned on, it loads, and emacs crashes hard, after displaying the "fontifying buffer..." progress bar. (I have xemacs-base 1.51 installed, says pui-list-packages.) I saw it happen on larger mail messages (like the bug-report message), on large lisp files, java files using jde, etc. The lisp and C backtrace I have attached are BTs from opening a .el file, which is also attached. Lisp backtrace follows: dispatch-non-command-events() # (condition-case ... . ((nil))) progress-feedback-dispatch-non-command-events() # bind (tmsg top frame value message label) append-progress-feedback(font-lock "Fontifying misc.el..." 0 nil) # bind (frame value message label) display-progress-feedback(font-lock "Fontifying misc.el..." 0) # bind (str) # (unwind-protect ...) # bind (args value fmt label) progress-feedback-with-label(font-lock "Fontifying %s..." 0 "misc.el") # bind (maybe-loudly end beg) font-lock-default-unfontify-region(1 22108 t) # bind (loudly end beg) font-lock-unfontify-region(1 22108 t) # bind (was-on font-lock-verbose font-lock-message-threshold aborted) # (unwind-protect ...) font-lock-default-fontify-buffer() # bind (font-lock-verbose) font-lock-fontify-buffer() # bind (on-p maximum-size arg) font-lock-mode(1) turn-on-font-lock() # bind (explicit-defaults) font-lock-set-defaults() run-hooks(font-lock-set-defaults) # bind (nomodes after-find-file-from-revert-buffer noauto warn error) after-find-file(nil t) byte-code("..."
