Bug description:  Magic methods __set/__get broken

Description:
------------
I've created a small class that implements the magic __set, __get and
__isset methods. Using PHP 5.1.6 I can assign an array to a "fake" instance
variable and then add elements to it. Doing the same using PHP 5.2.1 or
5.2.2 doesn't change the contents of the array. 

I've tried returning a reference from the __get method (e.g. changes the
function definition to "function &__get($key, $value) ...", but this
doesn't work either (although PHP doesn't complain about it).

If this wasn't supposed to work with PHP 5.1.6 how should I then implement
this to get the desired behaviour? If this isn't possible at all then that
means __set/__get are far less usable then before.

Reproduce code:
---------------
class Data
{
  private $m_data = array();

  function __set($key, $value) { $this->m_data[$key] = $value; }
  function __get($key) { return $this->m_data[$key]; }
  function __isset($key) { return isset($this->m_data[$key]); }

  function dump() { var_dump($this->m_data); }
}

$obj = new Data();
$obj->a = "a";
$obj->b = array();
$obj->b[] = '1';
$obj->b[] = '2';
$obj->b[] = '3';
$obj->dump();

Expected result:
----------------
array(2) {
  ["a"]=>
  string(1) "a"
  ["b"]=>
  array(3) {
    [0]=>
    string(1) "1"
    [1]=>
    string(1) "2"
    [2]=>
    string(1) "3"
  }
}

Actual result:
--------------
array(2) {
  ["a"]=>
  string(1) "a"
  ["b"]=>
  array(0) {
  }
}
