Emacs master branch: * emacs/lisp/font-lock.el (font-lock-fontify-syntactically-region): At line 26 of this function, appears: (setq state (parse-partial-sexp (point) end nil nil state 'syntax-table)) .. However, there is no goto-char or other way of setting point earlier in the function (except in one arm of an `if' form). Neither is point defined to have a defined setting at the entry to the function. This is a bug. -- Alan Mackenzie (Nuremberg, Germany).
