Description:
------------
setcookie() will not set a cookie. It worked for me in PHP 5.4.7, but upon upgrading to PHP 5.5.5 the cookie will no longer be set. I tested in Opera 12, Chromium, Chrome and Opera 15. 

NOTE: I filed it under Apache2 as I didn't know what to file it under.

Test script:
---------------
<?php
// Example
setcookie("A", "B");
?>

Expected result:
----------------
The cookie should be set.

Actual result:
--------------
The cookie isn't set.
