font-lock gets stuck!

Hi i am running XEmacs-21.4 and i ran into the following problem. When i tried to fontify this file: /tmp/v1.cxx: /* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ */ xemacs gets stuck and when i killed the proc i get this trace: Lisp backtrace follows: re-search-forward("^\\(\\(\\(\\sw\\|\\s_\\|[:~*&]\\)+[ ]+\\)\\(\\(\\(\\sw\\|\\s_\\|[:~*&]\\)+[ ]+\\)\\(\\(\\sw\\|\\s_\\|[:~*&]\\)+[ ]+\\)?\\)?\\)?\\([:*&]+[ ]*\\)?\\(\\(\\sw\\|\\s_\\|[:~*&]\\)+\\)[ ]*(" 84 t) # bind (highlights matcher keyword nkeywords iter old-progress progress bufname keywords case-fold-search loudly loudvar end start) font-lock-fontify-keywords-region(1 84 nil) # (unwind-protect ...) # bind (modified buffer-undo-list inhibit-read-only old-syntax-table buffer-file-name buffer-file-truename loudly end beg) font-lock-default-fontify-region(1 84 nil) # bind (loudly end beg) font-lock-fontify-region(1 84) # (unwind-protect ...) byte-code("..."
