Ah, yes.  I didn't understand your point, correctly.
Since it seems that this problem was fixed in BIND9's inet_pton.c,
I've just commited the fix which was taken from it:

http://www.freebsd.org/cgi/cvsweb.cgi/src/lib/libc/net/inet_pton.c.diff?r1=1.11&r2=1.12

Please try it, and let me know the result.

Sincerely,
