emacs hang up with bad-brackets cpp-file

[Oke Oldenburg]

Hi

when loading (or scrolling the loaded) file "fail.cxx" emacs freezes and 
goes on 100% cpu load until emacs.exe gets killed. No display update, no 
reaction on any keys or mouse events. Also the system "close" isnt 
processed.
(I'm using emacs 21.3 on windows, details see below)

Actions on my side:
- Starting emacs
- load fail.cxx
- when the bad line "m(n));" is visible, emacs freezes.
- when the line is not visible (e.g. if there are much more lines "  x;" 
in the file):
   - scroll down the buffer -> emacs freezes then


Here is my file "fail.cxx":

 >>> START of file:
#define W c)(c

int A()
{
}

int B()
{
   x;
   x;
   x;
   x;
   x;
   x;
   x;
   x;

   m(n));
}

int C()
{
}

<<< End of file

I assume the problem in a conflict of the not-nice define "c)(c" and the 
double close bracket, probably when calculating hilit.
The define (original its "#define CCCp char*)(const char*" ) is needed 
to have a short version of "(char*)(const char*)"
The doubled bracket were a result of cut and paste and should have been 
cleared in my next step, but the freeze occured before that ...

Can you duplicate the described behavior?

thanks for any help

Oke
