Description:
------------
[ sorry for english ] 
 
There is a problem with static properties initialized as 
an array in classes. 
 
In the following code, if you replace "public static $test 
= array();" by "public static $test;" or if you initialize 
the property with not an array ("public static $test = 
12;" for example), it works as expected. 

Reproduce code:
---------------
<?
class A {

	public static $test = array();

	public function set($var) {
		self::$test = $var;
	}

	public static function view() {
		var_dump(self::$test);
	}

}

class B extends A {

	public static function view() {
		var_dump(self::$test);
	}

}

$class = new B;
$class->set(array('key' => 'value'));

A::view();
B::view();
?>

Expected result:
----------------
array(1) { ["key"]=> string(5) "value" } 
array(1) { ["key"]=> string(5) "value" } 

Actual result:
--------------
array(1) { ["key"]=> string(5) "value" } 
array(0) { }
