No, the auto-trust-anchor-file directive is commented out in my conf
(can't use it with that domain) and I don't get an error like that.
The unbound-host is crashing with a segmentation fault (my translation
to "access violation" was incorrect) and the last lines of the log are:

Jun 12 11:51:19 libunbound[13639:0] debug: Forward zone server list:
Jun 12 11:51:19 libunbound[13639:0] info: DelegationPoint<www.xy.de.>: 0
names (0 missing), 2 addrs (0 result, 2 avail) parentNS
Jun 12 11:51:19 libunbound[13639:0] error: duplicate forward zone ignored.
Jun 12 11:51:19 libunbound[13639:0] debug: Forward zone server list:


Funny enough, the segfault seems to be happening while writing the log.
A trace is further down. I'd say it happens when libunbound is trying to
put out the Forward zone server list.

regards, jo
