Description:
------------
I guess that, sprintf function has a bug. Which command damages inserted values or texts.

Reproduce code:
---------------
$ONAYLAMAMAIL	= "

";

$member_securitycode = 34567823;
$member_firstname = "xx";
$member_lastname = "xx";
$username = "xx";
$password = "xx";
$member_username = "xx";
$member_mail = "xx@xx.com";

$mesaj = sprintf($ONAYLAMAMAIL, $member_firstname, $member_lastname, $username, $password, $member_securitycode, $member_username, $member_email, $member_securitycode, $username, $member_email);

echo $mesaj;

Expected result:
----------------
there should be get right $member_securitycode like 34567823 but sometimes it could be like 3456782 number.. It randomly crops a digit or a char (sometimes more than one char). I have fixed only loading php4.3.2 version, and the problem is solved.

Actual result:
--------------
I can show the bug to you if you wish. My server is running on php4.3.2 now. Because php4.3.3 has this bug.
