Description:
------------
Same as bug #38013 but different behaviour between PHP 4.3.10 and 5.2.5

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

function change (&$var) {
  $var += 10;
}

$var = 1;
++$var;
change($var);
echo "var=$var";
$var = 5;
change($var);
echo "var=$var";

$var = 1;
change(++$var);
echo "var=$var";
change($var = 5);
echo "var=$var";

?>


Expected result:
----------------
That one from php 4 :
var=12
var=12

Actual result:
--------------
in PHP 5:
var=12
var=2
