Description:
------------
When an object with a __set() method has its non-existent array containing variable set by empty bracket syntax, it just creates a new object variable for the array, as if __set() weren't even there.

Test script:
---------------
<?php
class Foo {
    public $_vars = array();

    public function __set($var, $value) {
        $this->_vars[$var] = $value;
    }
}

$foo = new Foo;
$foo->bar[] = 'value';
var_dump($foo);
?>

Expected result:
----------------
__set() method called
object(Foo)#1 (1) {
  ["_vars"]=>
  array(1) {
    ["bar"]=>
    array(1) {
      [0]=>
      string(5) "value"
    }
  }
}

Actual result:
