Description:
------------
PHP Version = 5.2.6.6

I cannot seem to enforce a class's __construct argument list by defining an abstract constructor in the base class. This can, however, be achieved as expected by using an object interface.

This was mistakenly reported as not working for interfaces either in bug #43557 (closed).

Test script:
---------------
class Type1 {} //for demo purposes
class Type2 {} //for demo purposes

abstract class BaseClass {
   abstract public function __construct(Type1 $foo, Type2 $bar);
}

class ExtendedClass extends BaseClass {
   public function __construct() {
      //expected - fatal error as argument list doesn't match
      //actually happens - nothing, script continues as normal
   }
}

interface SomeInterface {
   public function __construct(Type1 $foo, Type2 $bar);
}

class InterfacedClass implements SomeInterface {
   public function __construct() {
      //generates fatal error as expected
   }
}

Expected result:
----------------
Fatal error when declaring ExtendedClass and InterfacedClass as abstract and concrete method signatures are different.

Actual result:
--------------
Only a fatal error when declaring InterfacedClass, no error when declaring ExtendedClass.
