Description:
------------
calling a child classes static function from parent constructor generates error

Test script:
---------------
class A{
  public function __construct(){
    static::someFunc();
  }
 
  abstract protected static function someFunc;

}

Class B extens A{
  public function __construct(){
    parent::__construct();
  }
  protected static function someFunc(){

  }
}

$obj = new B();

Expected result:
----------------
I expect it to keep executing with no errors.

Actual result:
--------------
ErrorException with message 'Static function A::someFunc() should not be abstract'
