Description:
------------
zend.ze1_compatibility_mode when turned on doesn't honor the same methodlogy as 4.x when passing a class for some parameters - it passes by reference in functions like array_push();

this behavior was not in 4.3.x, and the only workaround is the clone keyword, which should be added in the 4.3.x tree for backwards compatability.

Reproduce code:
---------------
<?
class x { };

$first = new x;
$second = $first;
$container = array();
array_push($container, $first);

$first->first = " im in the first";

print_r($first);
print_r($second);
print_r($container);


Expected result:
----------------
x Object
(
    [first] =>  im in the first
)

x Object
(
)

Array
(
    [0] => x Object
        (
        )
)

Actual result:
--------------
x Object
(
    [first] =>  im in the first
)

x Object
(
)

Array
(
    [0] => x Object
        (
            [first] =>  im in the first
        )
)

zend.ze1_compatibility_mode => On => On

produces:


C:\php5-win32-latest>php c:\web\ze1_test.php
x Object

)

which is not the design of php4
