dhcpcd-discuss

I'm using dhcpcd on my FreeBSD router/gateway together with mpd5 (pppoe)
getting ipv6 /56 prefix from ISP and distributing it to my internal network.
After updating from 7.0.8 to 7.1.0 using exactly the same build and
configuration setup it crashes kernel when it starts and cause system halt.

dhcpcd.conf follows
------------------------------
duid
noipv4
noipv4ll
noipv6rs
ipv6only
release
option rapid_commit
option interface_mtu
option classless_static_routes
require dhcp_server_identifier
nohook resolv.conf, hostname, ntp, test, dump
allowinterfaces ng0 bridge0
interface ng0
    ipv6rs
    ipv6ra_noautoconf
    ia_pd 1 bridge0/0/64
-------------------------------------

ng0 is the default netgraph interface dynamically created by mpd5 and
bridge0 is my internal networking bridge interface.
This configuration worked flawlessly for years, even after upgrading to
FreeBSD 12.0. I had to revert to dhcpcd 7.0.8 until this issue fixed.
