Description:
------------
When accessing object properties directly witin object's parent (the one which object extends) the property acts as if it was public (no error).

Similar thing happens with protected constructors where new instance of a certain class can be created using "new" when the call is made inside of an object which is the parent or which extends the same parent.

Reproduce code:
---------------
class A {

	public function access()
	{
		$b = new B;	
		echo $b->property;
	}
	
}


class B extends A {

	protected $property = 'Should be protected';
	
}

class C extends A {
		
}

$c = new C;
$c->access();

$b = new B;
echo $b->property;

Expected result:
----------------
Fatal error: Cannot access protected property B::$property

Actual result:
--------------
Protection is broken 
Fatal error: Cannot access protected property B::$property
