Thanks for the questions, good for me to think about it some more.
Short response:
I don't think it is the FRR config, but the routes received that are
crashing it or ospf6d has some other issue.

I just upgraded from FreeBSD 11 to 12 and upgrade from quagga to FRR at

bgpd and ospfd work fine, but ospf6 doesn't work.? Not sure what I'm
going wrong.
If I commend out all the interfaces EXCEPT lo0, ospf6d does not crash.
What if you comment out just lo0? Running OSPF on a loopback
interface makes no since, your not going to be able to establish
a DR/BDR pair so OSPF can never really come up on that interface,
and if it did injecting any route from 127/8 into the OSPF lsdb
would be very bad!
Though I doubt this is the source of the illegal instuction trap
it is none the less a configuration issue.
Personally, I always put a 172.17.x.x IP on my lo0 and then advertise
that into my network. I don't make it part of the router config, but I
wanted a 'test device' to boot ospf6d and see it crash. Also, the docs
on FRR have an lo0.
I do advertise my 172.17.x.x IP on the loobpback: This is how I verify
OSPF is up -- the IPwill ping from other devices on the network when
OSPF is up. For IPv6, I put a whole /64 on the lo0. So many IPs in v6. :)

*** CRASH ***
Zebra process crashes after the ospf6 process has encountered some error
and shut down or are you indicatong that the OSPF6D process has crashed?
OSPF6d crashes, zebra just notes the client #32, the ospf6 process,
saying hello and goodbye.
If I run on the command line and don't background, it bombs after 7
seconds:
# ospf6d
Illegal instruction
...
What happens if you remove this lo0 section?
Still crashes, usually don't have lo0 in an a
Does ospf6 come up and run if you remove all the
route-map stuff your trying to do?
Sure, I can try a minimal setup. This config crashes in the same way:
