Description:
------------
PDOStatement::fetch with PDO::FETCH_CLASS works fine, until I tried to use it with parent class private properties... See the test script.

Test script:
---------------
class Animal
{
	private $color;
	public function getColor()
	{
		return $this->color;
	}
}
class Cat extends Animal
{
}

$statement->setFetchMode(PDO::FETCH_CLASS, "Cat" );
$someCat = $statement->fetch();

echo $someCat->getColor();	//empty
print_r( $someCat );
/*
now have strange output like:
[color:Animal:private] => 
[color] => grey
*/

Expected result:
----------------
All private properties of parent class have to be set same way as public and protected ones.

Actual result:
--------------
Private property of parent class still empty :(
