Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to
report
a bug at http://bugs.php.net/how-to-report.php

You cannot return a reference to a literal, if you rewrite your code in
the following manner it works properly.

<?php
$a = 'hello'; $b =& $a;
$a = &f_test();

echo "* a = {".$a."}, b = {".$b."}\n";

function &f_test() {
        $a = 'tested';
        return $a;
}
?>

Description:
------------
This bug is a change of Assignment by reference behavior bewteen Php
versions <= 5.0.4 and the last 5.0.5.

In Php 5.0.5 when a variable is re-assigned by reference directly using
a function, then the variable is assigned by value.  

Reproduce code:
---------------
<?php

$a = 'hello';
$b =& $a;       
$a =& f_test();

echo "* a = {".$a."}, b = {".$b."}<br>";

function f_test() {
	return 'tested';
}

?>

Expected result:
----------------
* a = {tested}, b = {hello}

Actual result:
--------------
* a = {tested}, b = {tested}
