Description:
------------
PHP does not behave as expected when passing arguments by reference into
a 
function that are passed out again by reference.

IMO, the below test script should behave equivalently to the following
code 
(which produces the expected result):

$b = 'foobar';
$a =& $b;
$c =& $a;
$c[2] = 'z';

var_dump($c);
var_dump($b);

Test script:
---------------
function &ref(&$a)
{
  return $a;
}

$b = 'foobar';
$c = ref($b);
$c[2] = 'z';

Expected result:
----------------
string 'fozbar' (length=6)
string 'fozbar' (length=6)

Actual result:
--------------
string 'fozbar' (length=6)
string 'foobar' (length=6)
