Description:
------------
func_get_arg() can be used as argument to function only once.

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

function doTitle($a = NULL, $b = NULL) {
  print "doTitle: $a, $b\n";
}

function doHead() {
  doTitle(func_get_arg(0));
  doTitle(func_get_arg(1));
  doTitle(func_get_arg(0), "3");
  doTitle(func_get_arg(0), func_get_arg(1));
}

doHead("1", "2");

?>


Expected result:
----------------
doTitle: 1,
doTitle: 2,
doTitle: 1, 3
doTitle: 1, 2


Actual result:
--------------
doTitle: 1,
doTitle: 2,
doTitle: 1, 3

Fatal error: func_get_arg(): Can't be used as a function parameter in
/tmp/func_get_arg.php on line 11
