Message-ID: <o7S-KiWzMHdRKGoozeP71js7G2Pd1hTVL-7EanIJJDvmt8jsf2hfhc-C824wNLRg5hGkJkLLA7tCeCye2-SCpmfZ3LBzZwsP5PJQWcbSIiM=@protonmail.com> (raw)

Here's a minimal example (sorry I didn't try to do this earlier):
(with-temp-buffer
(insert "foo\nbar\nbaz")
(narrow-to-region 4 5)
(message "%s" (line-number-at-pos 1 t)))
On the latest master (ef7a6eec20), this errors with
Args out of range: 1, 4, 5
But on emacs-27.2, it prints "1".
From what I can tell, this is because the lisp version of line-number-at-pos
allowed the argument to be outside the visible range, and it widened before
counting lines to allow this.
