isc_boolean_true) failed
Oct 22 22:08:47 (none) named[938]: exiting (due to assertion failure)

I have not had time to look into the cause of the assertion failure, but
thought that I should post that I'm seeing the issue, just in case I'm not
the only one.

Zones: Standard zones with IPv6. No DNSSEC records.
Run-time: DNSSEC validation enabled - with dlv.isc.org lookups.

Configuration - pretty standard:
configure --prefix=/usr --with-openssl=/usr/local/ssl --mandir=/usr/man --wi
th-run-dir=/var/run --sysconfdir=/etc --localstatedir=/var CFLAGS=
"-DDIG_SIGCHASE=1"

One modification - to the empty zones (patch follows):

-------------------------------------
In other words, I turn on the ignored zones, plus I add the IPv6
documentation and multicast zones to the list.
