Strange ipf ipv6 issues on alpha

[Sten Spans]

I have an alpha running freebsd 4.9p2,
and somehow ipf seems to have gone on strike
just recently. I'm guessing this started ocurring
when going from 4.9p1 to p2.

towel# ipf -6 -F o
towel# cat /etc/ipf6.rules
pass out quick on fxp1 to gif0:3ffe:8114:1000::2a8 from 3ffe:8114:2000:10E0::/60 to any
pass out quick on fxp1 to gif0:3ffe:8114:1000::2a8 from 3ffe:8114:1000::2a9 to any
towel# ipf -6 -f /etc/ipf6.rules
towel# ipfstat -o -6
pass out quick on fxp1 to gif0:v  from 3ffe:8114:2000:10e0::/60 to any
pass out quick on fxp1 to gif0:v  from 3ffe:8114:1000::2a9/128 to any

The ipv6 address folowing gif0 is replaced by some binary character.
Anyone got a clue ?

( please cc me, since I don't subscribe to fbsd-net )
