Hello, I've got "Zero Sized Reply" when I try to replace a long string with PCRE.

Test script:
for($i=0; $i<1024; $i++)$strtest.=chr(rand(1, 254));
for($i=0; $i<1024*512; $i++)$strtest.=chr(rand(1, 254));
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:
The requested URL could not be retrieved

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

The following error was encountered: 
Zero Sized Reply 

Squid did not receive any data for this request. 

Your cache administrator is *******.
