Description:
------------
Type hinting prevents passing NULL of non related objects as argument.
An error is give on where the function is defined instead of where it
is called. This make it hard to track down the bug, because it could be
called a 100 times from different files, while only one is wrong.


Reproduce code:
---------------
<?php
  class X {
    public function fa() {}
  }

  class Y {
    public function fb() {}
  }

  function f(X $y) {
    $y->fa();
  }

  f(new Y());
?>


Expected result:
----------------
Would like an error on line 14 [   f(new Y()); ]

Actual result:
--------------
Give an erorr on line 11 [ function f(X $y) ].
