Here is a way to recreate the crash:

$ cat /etc/rtadvd.conf
tun6:addr="fd00:1234::1":prefixlen#64:


for I in `jot 20 1`; do
        ifconfig tun6 create
        ifconfig tun7 create
        ifconfig tun7 destroy
        ifconfig tun6 destroy
done
ifconfig tun6 create
ifconfig tun6 link0
ifconfig tun6 inet6 fd00:1234::1


Now start the daemon:
rtadvd -d tun6

And the client:
rtsol -d tun6

If it doesn't crash restart the daemon and try again.
