Description:
------------
See the code below: 
 
An object of ClassA is passed to FuncB, which calls FuncA 
with the return-by-reference operator. FuncA is not 
designed to return by reference. 
 
The reference count seems to get wrong by doing that so 
the object is discarded when FuncB returns. 
 

Reproduce code:
---------------
<?php
class ClassA { }

function FuncA($obj) {
    return $obj;
}

function FuncB($obj) {
    $dummy = &FuncA($obj);
}

$obj = new ClassA();
FuncB($obj);
$str='This is a string'
var_dump($obj);


Expected result:
----------------
object(ClassA)#1 (0) { } 
 

Actual result:
--------------
string(16) "This is a string"
