Description:
------------
If the match for a regex is very long, it fails.

Reproduce code:
---------------
$a='A';
for ($i = 0; $i < 1024; $i++) $a.='a';
$a.='A';
var_dump(preg_match('/A(.*?)A/', $a, $m));

$a='A';
for ($i = 0; $i < 131072; $i++) $a.='a';
$a.='A';
var_dump(preg_match('/A(.*?)A/', $a, $m));



Expected result:
----------------
int(1)
int(1)


Actual result:
--------------
int(1)
int(0)
