We are chasing down a similar issue on another ticket. When we get that sorted out we will send you a patch to check if it fixes the crash issue. As for the empty zone, it should be replaced if if a explicit declaration comes it. Similarly if a explicit declaration for a potential empty zone is removes we should check if we should instantiate it. -- Mark Andrews, ISC 1 Seymour St., Dundas Valley, NSW 2117, Australia PHONE: +61 2 9871 4742 INTERNET: marka@isc.org
