[Bug: 21.4.12] lazy-lock causes infinite loop in XEmacs

================================================================ Dear Bug Team! I just upgraded my XEmacs packages to the latest versions available and I see that lazy-lock breaks XEmacs. By breaks I mean that XEmacs gets into an infinite loop and I am unable to C-g or even C-c from the terminal. I have to do a C-z and kill %1 to quit XEmacs. I am using XEmacs-21.4.12. I have no idea what is wrong but an easy way to reproduce it is to have just the following in your .xemacs/init.el (require 'lazy-lock) (add-hook 'font-lock-mode-hook 'turn-on-lazy-lock) ;; lazy-lock doesn't have a variable for its modeline name, so we have ;; to do a bit of surgery. (and (assoc 'lazy-lock-mode minor-mode-alist) (setcdr (cdr (cadr (assoc 'lazy-lock-mode minor-mode-alist))) "")) and the following in your .xemacs/custom.el (custom-set-variables '(lazy-lock-minimum-size 50000) '(lazy-lock-stealth-time nil) '(lazy-lock-mode 1 nil (lazy-lock))) You should see that XEmacs goes into an infinite loop trying to fontify *scratch*. If not, I will be very interested to hear from you so that I can figure out what is wrong with my build of XEmacs. -kitty. ================================================================ System Info to help track down your bug: --------------------------------------- uname -a: Linux samba 2.4.20aa1 #10 SMP Tue Mar 4 21:57:25 CST 2003 i686 i686 i386 GNU/Linux ./configure '--prefix=/usr' '--exec-prefix=/usr' '--bindir=/usr/bin' '--datadir=/usr/share' '--libdir=/usr/lib' '--mandir=/usr/man/man1' '--infodir=/usr/share/info' '--with-gpm=no' '--with-sound=native' '--with-pop' '--mail-locking=lockf' '--debug=no' '--error-checking=none' '--with-database=berkdb' '--with-ldap=yes' '--pdump' XEmacs 21.4.12 "Portable Code" configured for `i686-pc-linux'.
