Description:
------------
When processing this code. The parsing ends on the preg_match function.
$t has 475 characters in it. Remove one char and the script works again.

PS.: This was also tested with php 5.1.4 on gentoo linux without any problems.

Reproduce code:
---------------
$t = "---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------";
$text = "
<p>".$t."</p>

<p>Some text doesn't matter how long</p>
";

//echo strlen($t);
	$pattern = '/<p([a-z "=]*)?>((.)*?)<(\/)?p>/';
	preg_match($pattern, $text, $paragraphs) or die("died");

echo $paragraphs[0];

Expected result:
----------------
$t should be displayed no matter how many chars it has (though considering limitation of PCRE).

Actual result:
--------------
Script ends on preg_match after a few seconds of 100% CPU load. No errors no crashes.
