Description:
------------
When $this is stored by reference in a PHP array, itself stored in a
property, then function call_user_func_array() is able to recognize the
reference only if called in the same local context where $this is
referenced. In other words, the reference seems to be lost for
call_user_func_array().

The bug does not occur with PHP 5.2,
It does occur with both PHP 5.3.0 and PHP 5.3.1. Not yet tested with
PHP 5.3.2

Note that if we use a global variable instead of a property, then the
bug does not occur.



Reproduce code:
---------------
<?php

function f_test(&$obj) {
        $obj->prop++;
        echo "prop=".$obj->prop." <br>\r\n";
}

class clsTest {
        public $prop = 0;
        public $arg_array = false;
        function meth() {
                if ($this->arg_array===false) $this->arg_array = array(&$this);
                echo 'arg_array[0] '.(($this->arg_array[0]===$this) ? ' is the 
same
instance' : ' is not the same instance').' than $this'."  <br>\r\n";
                call_user_func_array('f_test', $this->arg_array);
        }
}

$oTest = new clsTest;
$oTest->meth(); // OK
$oTest->meth(); // ERR

?>

Expected result:
----------------
arg_array[0] is the same instance than $this
prop=1
arg_array[0] is the same instance than $this

Warning: Parameter 1 to f_test() expected to be a reference, value
given in D:\www\bug.php on line 14

Actual result:
--------------
arg_array[0] is the same instance than $this
prop=1
arg_array[0] is the same instance than $this
prop=2
