[Message part 1 (text/plain, inline)]
Hi,

I'm using emacs 26.3.

Call:

(font-lock-add-keywords
 'c-mode
 '(
   ("\\<XXX\\>[^;]*;" 0 'font-lock-function-name-face t)))

Then visit a .c file with this line:

  XXX("aaa");

The line is rendered with font-lock-function-name-face, except the second " which has font-lock-warning-face.
Somehow emacs thinks there is an unfinished string literal.

 - Jörg

I'm able to reproduce this in Emacs 26, but not in Emacs 27, so I think
this has been fixed by now.
