Today I tried to run PHP-GTK with ZE2 changes against current CVS and it segfaulted. I traced it to the fact that PG(http_globals)[TRACK_SERVER_VARS] is no longer available if $_SERVER is not present in the PHP code, due to the changes Zeev (I think) made in order to improve efficiency. I don't quite agree with the way it works right now.
Well, it works well though :) All you have to do is hint PHP that you're going to touch it, and it will be available for you immediately. To do that, simply call:
zend_is_auto_global("_SERVER", sizeof("_SERVER")-1 TSRMLS_CC);
and you're done. ext/standard/info.c already makes use of this.
