Subject: bug#50640: 28.0.50; incorrect highlighting in C++ mode
Date: Fri, 17 Sep 2021 14:57:31 +0200 [thread overview]
Message-ID: <87czp79x6s.fsf@vinc17.net> (raw)
Consider a test.cc file containing:
if (xMin - xt < t3Font->glyphX ||
yMin - yt < t3Font->glyphY ||
xMax - xt > t3Font->glyphX + t3Font->glyphW ||
yMax - yt > t3Font->glyphY + t3Font->glyphH) {
}
(this comes from the xpdf source) and open it with "emacs -Q".
The first two "xt" and "yt" are highlighted in green instead of
remaining in black. If I remove the last condition as follows
and reopen the file:
if (xMin - xt < t3Font->glyphX ||
yMin - yt < t3Font->glyphY ||
xMax - xt > t3Font->glyphX + t3Font->glyphW) {
}
then only the "yt" is highlighted incorrectly.
