Bug description:  Accessing overloaded member via foreach does not work

Description:
------------
Using an overloaded property from an object instance directly in a foreach
fails. If you assign the property (or a reference to it) to a variable
first it works fine. This is reproducable. 

Interestingly enough, I see a strange problem with inheritance and
overloaded members. I am unable  to reproduce it in a simple example. I
will continue to work that. Basically, you get the same fatal error as
here BUT on assignment to a member variable of the parent class that is
not overloaded. It's bizzare. As soon as I remove the __get/__set from the
child, the parent method works fine again from an instance of child. Again,
simple examples do not seem to reproduce. <sigh>

Reproduce code:
---------------
class Son
{
    protected $m_aActions;
    
    function __construct(&$aActions)
    {
        $this->m_aActions = $aActions;
    }
    
    function __get($mName)
    {
        $mRetval = null;
        
        switch($mName)
        {
            case("Actions"):
            {
                $mRetval = $this->m_aActions;
                break;
            }
        }
        
        return $mRetval;
    }
}

$aActions = array("add", "delete");
$oSon = new Son($aActions);

$aActions = $oSon->Actions;
var_dump($aActions);

foreach($oSon->Actions as $strAction)
{
    echo $strAction . "\n";
}



Expected result:
----------------
array(2) {
  [0]=>
  string(3) "add"
  [1]=>
  string(6) "delete"
}

add
delete

Actual result:
--------------
array(2) {
  [0]=>
  string(3) "add"
  [1]=>
  string(6) "delete"
}

Fatal error:  Cannot access undefined property for object with overloaded
property access
