Also the code I have uses namespaces.

Description:
------------
When inheriting from a class and calling constructor with invalid arguments, it won’t throw any
error, but die silently. There is no information in web server log or PHP-FPM’s logs and
nothing is returned to client either.



Test script:
---------------
class SlamObject {

}

class Utility extends SlamObject {

}

abstract class AbstractHandler extends Utility {

    protected $version;

    protected $session;

    protected $output;

    public function __construct($session, $output, $version) {
        $this->session = $session;
        $this->output = $output;
        $this->version = $version;
    }

}

class Foo extends AbstractClass {

}

$foo = new Foo();

Expected result:
----------------
At the point of Foo, fatal error is thrown telling that you called constructor with wrong arguments.

Actual result:
--------------
Silent death at this point with no information anywhere.


------------------------------------------------------------------------
