Description:
------------
There is a memory leak when the same argument name is used 2 times in a function 
declaration.

Test script:
---------------
<?php
function foo($unused = null, $unused = null, $bar = array()) {
    return 1;
}
foo();

Actual result:
--------------
==67447== 32 bytes in 1 blocks are definitely lost in loss record 17 of 94
