4.4.1 to 4.4.8 base_url php spark closes..

Hi,
I'm working on updating to 4.4.8 and my base url is defined like below.

Code:

public string $baseURL = BASE_URL;

in config/Constants.php I have

Code:

$base_url = (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == 'on' ? 'https://' : 'http://') . $_SERVER['HTTP_HOST'] . dirname($_SERVER['SCRIPT_NAME']) . (substr(dirname($_SERVER['SCRIPT_NAME']), -1) == '/' ? '' : '/');

defined('BASE_URL') || define('BASE_URL', $base_url);

when I run php spark on 4.4.1 it works fine, but on 4.4.8 it just exits out, and doesn't run the localhost server.

if i replace the $baseURL with http://localhost:8080/ it works, but I need the dynamic url. So why is 4.4.8 exiting out when 4.4.1 doesn't? I don't get any error, it just goes back the typing commands in command prompt, and doesn't run the local server.

Any help would be appreicated.
