Bug description:  Operation is amusing when a constant is set up by __set to the 
overloaded class

Description:
------------
When __set is called to the class by which the overload was carried out, 
operation by FOO and constant ('FOO') is different.

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

define( 'FOO', 'BAR' );

class line
{
    var $_data = array();
    
    function set( $key, $value )
    {
        $this->_data[$key] = $value;
    }
    function get( $key )
    {
        return $this->_data[$key];
    }
}

class Info
{
    var $_data = null;
    
    function Info( & $line )
    {
        $this->_data = array( & $line );
    }
    function __set( $key, $value )
    {
        $data =& $this->_data;
        $data[0]->set( $key, $value );
        return TRUE;
    }
    function __get( $key, &$value )
    {
        $data = $this->_data;
        $ret =& $data[0]->get( $key );
        $value = $ret;
        return TRUE;
    }
}

overload( 'Info' );

$test = new Info( new line );

// [case 1 = fail]
$test->x = FOO;
echo $test->x;

// [case 2 = success]
//$test->x = constant('FOO');
//echo $test->x;

// [case 3 = crash!!!!!]
// When it calls simultaneously
//$test->x = FOO;
//$test->y = constant('FOO');

?>

Expected result:
----------------
//[case 1]
BAR

//[case 2]
BAR

//[case 3]
BAR
BAR

Actual result:
--------------
//[case 1]
xR     (why???)

//[case 2]
BAR    (ok!!!)

//[case 3]
segfault!!!!!
