In my last comment I dumped first $b and then $c, so the output hasn't
changed
from PHP 5.3.2.

Sorry, but the test script produces still the wrong output for me.
$ php -v

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)
