bug#24377: 25.1; CC-Mode (C++) uses font-lock-type-face for ordinary var


From: Bastian Beischer
Subject: bug#24377: 25.1; CC-Mode (C++) uses font-lock-type-face for ordinary variable
Date: Tue, 06 Sep 2016 13:16:41 +0200

This piece of C++ code is wrongly fontified by CC-Mode:

int b = 5;
int a = (b*3);

Reproduce as follows:

1) emacs -Q
2) Open file "test.C"
3) Paste snippet in buffer
4) Place cursor over "b" in second line
5) M-x describe-face -> font-lock-type-face

This appears to be correlated with the presence of the opening
parentheses and the '*' character, because:

1) int a = b*3;
does not have this problem

2) "b" gets fontified incorrectly after entering the '*' character:
int a = (b*
