Bug description:Assignment operator assigns by reference on arrays containing objects.

Description:
------------
When assigning one array to another array that contains a collection of
objects, 
the assignment is by reference.

Test script:
---------------
<?php
$obj = (object) null;
$obj->name = 'Joe';

$arrA = array($obj);
$arrB = array();

$arrB = $arrA;

$arrB[0]->name = 'Mary';

print_r($arrA);
print_r($arrB);

Expected result:
----------------
Array
(
    [0] => stdClass Object
        (
            [name] => Joe
        )
 
)

Array
(
    [0] => stdClass Object
        (
            [name] => Mary
        )
 
)

Actual result:
--------------
Array
(
    [0] => stdClass Object
        (
            [name] => Mary
        )
 
)

Array
(
    [0] => stdClass Object
        (
            [name] => Mary
        )
 
)
