Description:
------------
Trying to overload SplObjectStorage __construct(),
but got an fatal error: Cannot call constructor

Notice that in manual
http://php.net/manual/en/class.splobjectstorage.php
class SplObjectStorage does not contain constructor, at least public.



Test script:
---------------
Class Foo extends SplObjectStorage
{
	public function __construct()
	{
		parent::__construct();
	}
}

$foo = new Foo();

Expected result:
----------------
It should work

Actual result:
--------------
Fatal error: Cannot call constructor
