25.1.50; Wrong fontification in c-mode fired by search-forward

[Alan Mackenzie]

Hello, Tino.

You were completely right! I've now fixed that glitch with `eq', and
C-s'ing to "for_each_frame" now causes "void" to be properly fontified.

Is the problem with "void" now completely fixed?

Hello Alan,
i found one way to reproduce the new problem. See below.

Hi Alan,
Both show now FOR_EACH_FRAME with default face.
In clear_image_caches `void' appears with default face
instead of green color as before the patch (see attached pics).

I can't reproduce this.

It happens after commit: 33f856ba
*) It's important that you reach the offended part of the buffer with
a search (C-s).
*) If you try
M-g g 1600 RET
the fontification looks OK.
emacs -Q src/image.c
C-s for_each_frame
C-s
;; Look the color of 'void' or 'clear_image_caches'.
M-x c-mode RET
Maybe related with the warning you mentioned in emacs-devel?
Warning: reference to free variable ‘eq’
Take a look in the messages below: they mention one error that seems
related with this 'eq' warning.

Congratularions! The 'void' problem is gone.
