This was a problem on all platforms and I believe it has now been fixed by a check-in 2009-02-07. Please let me know, thanks!

I have not noticed performance problems here but there have been
significant changes from 01/28 through today 02/04 and it is possible
there are problems under some usage conditions.  First, could you
test again using current CVS (including 02/04 changes)?  Also, is
there an easy way to obtain the 100% CPU usage cases in a mode that
comes with emacs?  What OS X version are you on?

Yes, today 02-04 is the same, and I am using OSX 10.5.6.

I am sorry but I am unable to reproduce it in other simple setup.

However, we seem to trace down that the issue is about regular
expression matching, as also mention in:
there are some clue about function "re-search-forward"

OK, thanks. There were no OS X-specific changes in the RE area, and it sounds like other platforms are experiencing similar issues.
