Description:
------------
array_diff_assoc in PHP5 seems to ignore items whose values  are objects. This should be irrelevant as this function takes only keys as reference for comparison. See code.


Reproduce code:
---------------
class Foo	{
	var $dato;	
	function Foo($dato)	{
		$this->dato = $dato;	
	}
}

$array1 = array ("a" => new Foo(5), "b" => new Foo(2), "c" => "azul", "rojo");
$array2 = array ("a" => new Foo(5), "amarillo", "rojo");
$result = array_diff_assoc ($array1, $array2);

print_r($result);

Expected result:
----------------
PHP 4.3.8:

Output:
Array
(
    [b] => foo Object
        (
            [dato] => 2
        )

    [c] => azul
    [0] => rojo
)

Correct.

The same code with PHP 5.0.4:
Output:
Array
(
    [a] => Foo Object
        (
            [dato] => 5
        )

    [b] => Foo Object
        (
            [dato] => 2
        )

    [c] => azul
    [0] => rojo
)

which is not the same, and not correct in PHP5: [a] item should not be there.
