Bug description: reference count gets wrong when return-reference-calling a normal
function
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"
