Description:
------------
given an abstract class Foo which has a constructor public:

abstract class Foo{
 public function __construct (){
    echo "Foor ::";
 }
}

and a concrete class(Bar) that extends Foo, but the latter has its constructor protected:

final class Bar extends {
  protected function __construct () {
   parent:: __construct (); 
   echo "bar";
  }
}

It generates a fatal error.

This is expected behavior of normal methods, but not for constructors

Test script:
---------------
abstract class Foo{
    public function __construct(){
        echo "Foo::";
    }
}

final class Bar extends Foo{
    protecte function __construct(){
        parent::__construct();
        echo "bar";
    }
    
    public static function bar(){
       new self();
    }
}

Bar::bar();

Expected result:
----------------
Foo::bar

Actual result:
--------------
Fatal error: Access level to Bar::__construct() must be public (as in class Foo) in /var/www/index.php on line 17
