auto_globals_jit breaks $_SERVER var

["Artzi, Yoav \(Yoav\)" <artzi@xxxxxxxxx>]

I have the following in my php.ini:
register_globals = Off
register_long_arrays = Off
register_argc_argv = Off
auto_globals_jit = On
 
The following PHP code prints nothing:
<?php
        $webroot = $_SERVER['DOCUMENT_ROOT'];
        $server = $_SERVER["HOST"];
        $file = $_SERVER["SCRIPT_FILENAME"];
        $transport = $_SERVER["REQUEST_TRANSPORT"];
        $port = $_SERVER["SERVER_PORT"];
        print "$webroot";
        print "$server";
        print "$transport";
?>
 
The rest of the php.ini is like php.ini-recommended that comes with the
source. Any idea what might be the problem?
 
Thanks,
 
Yoav.
