Subject: bug#55798: font-lock-fontify-syntactically-region uses point without initializing it.
Date: Sat, 4 Jun 2022 19:17:42 +0000 [thread overview]
Message-ID: <Ypuv1oRGCf1nf+hy@ACM> (raw)
Hello, Emacs.
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.
