Description:
------------
See reproduce code.

php.ini is stock / no changes.

Reproduce code:
---------------
<?php
// a class that does nothing
class something{
	function nothing(){
		}
	}
// a pass-by-value function that modifies a member's member
function pass_by_value($value){
	$value->member->val = 1;
	}
// create a something with a member something
$object = new something;
$object->member = new something;

// call nothing, then call pass_by_value and print results
$object->member->nothing();
echo "member->val should be empty!\n";
pass_by_value($object);
print_r($object);
?>

Expected result:
----------------
$object->member should be empty

Actual result:
--------------
$object->member->val == 1
