Trying to add rule into ipfw with table of IPv6 addresses produces coredump.
But if I add single rule for IPv6 address ipfw acts normal.
Machine has IPv6 address on interface? but it does not matter. Without IPv6 on any interface I got the same coredump.


How to reproduce:
     kldload ipfw
     ipfw table 1 create
     ipfw table 1 add 2a03:2480::/32
     ipfw add allow ip6 from 'table(1)' to me6 keep-state

Expected result:
     00XXX allow ip6 from table(1) to me6 keep-state

Actual result:
     Segmentation fault (core dumped)

It looks like your system isn't 11.0-STABLE.
Do you have option VIMAGE in the kernel config?
If so, it's probably the same problem that was described and fixed in https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=212649

Switched to r308635, GENERIC kernel. Same problem with coredump.
