Subject: bug#213: Emacs hangs (font-lock-mode)
Date: Thu, 8 May 2008 10:19:02 +0200

Hello!

Emacs hangs during font-lock-mode (cc-mode).
How to reproduce:

Copy the C++ code below, into a buffer (e.g. tmp.cpp) with cc-mode and
font-lock-mode ON, and the go ahead and try changing
the line
#include "iostream"

to

#include <iostream"

.... Emacs should hang!

Which Emacs ??? ->
GNU Emacs 22.1.1 (i486-pc-linux-gnu, GTK+ Version 2.12.0)
 of 2008-05-02 on terranova, modified by Ubuntu

'hope this can be reproduced and solved!

Regards,
Albert
