Description:
------------
Before submitting a bug, I consulted with Phillip Hazel, the maintainer of PCRE.  He tested up to over 400k of data with PCRE and had no problems.  So, I am thinking this is a PHP issue.

Basically, (.+?) will not match over 99,997 bytes.  This worked in PHP 5.0 and all previous versions I have used.

Reproduce code:
---------------
<?php

$string = "<tag>".str_repeat("x", 99997)."</tag>";

if(preg_match('/<tag>(.+?)<\/tag>/', $string, $match)){
    echo "Match 99997!\n";
}


$string = "<tag>".str_repeat("x", 99998)."</tag>";

if(preg_match('/<tag>(.+?)<\/tag>/', $string, $match)){
    echo "Match 99998!\n";
}

?>

Expected result:
----------------
Match 99997!
Match 99998!

Actual result:
--------------
Match 99997!
