Bug description:  after $var =pack(...) with 'N' flag, if use $var in $tmp[$var]='v' 
key is empty

just see code
<?
error_reporting(E_ALL);

$aa = pack("N",127);
$bb = pack("N",65);
$cc = pack("N",121344231);

echo "$aa\n";
echo "$bb\n";
echo "$cc\n";

$tmp=array();

$tmp[$aa] = "aa";
$tmp[$bb] = "bb";
$tmp[$cc] = "cc";

var_dump($tmp);
?>

output:

A
;��
array(3) {
  [""]=>
  string(2) "aa"
^^^^^^^ but needed [""] => "aa" ???
  [""]=>
  string(2) "bb"
  [";��"]=>
  string(2) "cc"
}

WHY ?
