Description:
------------
If we doing a for on a curl_multi_add_handle, Apache shut down without reason...
We can do 127 time, but no 128 (0111 111b)...
The problem come from the function not from the variable $i !

Reproduce code:
---------------
<?
$mh=curl_multi_init();
$ch = curl_init('http://www.example.com');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
for($i = 1; $i <= 128; $i++)
{
 $conn[$i] = curl_copy_handle($ch);
 curl_multi_add_handle ($mh,$conn[$i]);
}
...
?>

Expected result:
----------------
No error

Actual result:
--------------
An error
