Description:
------------
When register_globals=on is set the values of $HTTP_HOST and $SERVER["HTTP_HOST"] conatin not always the same.

Sometimes $HTTP_HOST is empty while $SERVER["HTTP_HOST"] contains the expected value.

After a reload it mostly works again. I cannot reproduce the error.

This error also occurs with PHP-4.3.2

Reproduce code:
---------------
print $HTTP_HOST."\n";
print $SERVER["HTTP_HOST"]."\n";

Expected result:
