Description:
------------
When trying to use preg_match I'm not getting the expected result. As you can see, $chiche var should have one element, and it's empty. I've tested same script with version 5.3.3 and works perfectly fine. Also, I'm not getting any error, although I've setted up error_reporting(E_ALL).
Best regards!

Test script:
---------------
<?php

error_reporting(E_ALL);

$res = "hola";
$res = preg_match("/hola/", $res, $chiche);

var_dump($chiche);

Expected result:
----------------
I expect to see :

array(1) {
  [0]=>
  string(4) "hola"
}





Actual result:
--------------
I see:

 array(0) { 

}
