Out of curiosity, what version of PHP are you using?

If you're running PHP 5.2.0 or later, then the problem may be
related to the pcre.backtrack_limit configuration setting, which
was added in PHP 5.2.0 .  This setting limits the amount of
work that pcre will perform in pattern matching, and the default
setting of 100,000 means that the limit could be reached fairly
early on medium-sized pages.

I'll see about adjusting the pattern match to be a bit more
efficient, but you might also try 

    ini_set('pcre.backtrack_limit', 1000000);

and see if that resolves the problem.
