Description:
------------
The changelog states:

> Improved performance of array_merge() and func_get_args() by
eliminating useless copying.

I think I found a bug related to this change. If it's not fixed it
should at least be documented.

Test script:
---------------
From http://3v4l.org/U40T0

<?php
class f
{
    function f(&$e){}
}

function getNew()
{
    $a = func_get_args();
    $c = array_shift($a);

    $r = new ReflectionClass($c);
    return $r->newInstanceArgs($a);
}

$e = new stdClass;

var_dump(getNew('f', $e));

Expected result:
----------------
object(f)#3 (0) {
}

Actual result:
--------------
Warning: Parameter 1 to f::f() expected to be a reference, value given
in /in//in/U40T0 on line 14

Warning: ReflectionClass::newInstanceArgs(): Invocation of f's
constructor failed in /in//in/U40T0 on line 14
NULL
