Description:
------------
If you store an array with an object inside the object is not stored

Reproduce code:
---------------
class whatever {
};

$a = new whatever();
$z = array(1, $a);
apc_store("hello", $a);
apc_store("hello2", $z);

var_dump(apc_fetch("hello")); //brings the correct object
var_dump(apc_fetch("hello2")); //brings the array 0=>1, 1=>NULL


Expected result:
----------------
bring array 0=>1, 1=>object

Actual result:
--------------
bring array 0=>1, 1=>NULL
