Description:
------------
Hello, I've got "Zero Sized Reply" when I try to replace a long string
with PCRE.
Test script:
---------------
<?php
$strtest='';
for($i=0; $i<1024; $i++)$strtest.=chr(rand(1, 254));
$strtest.='B';
for($i=0; $i<1024*512; $i++)$strtest.=chr(rand(1, 254));
$strtest.='signature';
for($i=0; $i<1024; $i++)$strtest.=chr(rand(1, 254));
preg_replace('/b(?:.(?!signature))*.(sig.+)/sim', 'null${1}',
$strtest);
?>
Expected result:
----------------
blank page
Actual result:
--------------
ERROR

While trying to retrieve the URL: *******
