With a large pre-processed C file GNU Emacs swallows all CPU power

[Peter Dyballa]

Hello!

This C code file from X11R7.1 (in xserver/GL/apple)

C -rw-r--r--  1 pete pete    43948 2006-11-12 15:09 aglGlx.c

when pre-processed, empty lines removed,

is opened in GNU Emacs, it happens, that GNU Emacs swallows all CPU  
power and becomes very unresponsive. Often only an xkill works. Doing  
an i-search in this buffer quite surely leads to this effect. Or  
putting the X client into the background while the buffer can be in  
the background, too. Used with -Q as argument. The same can be  
observed with GNU Emacs 22.0.50.
