There's something subtly wrong here, but I can't track it down.  

IPv4 addresses always work fine.  But if compiled with --enable-ipv6, IPv6
addresses only seem to cause some sort of memory corruption.  (I get
segfaults from free() or freeaddrinfo(), depending on what interface to
the library I use.)

I can't seem to track it down because gdb gets very confused -- for 
example, I can set a breakpoint, print out some values, do "step" and have 
it report that the program terminated with exit status 1, even though 
there is no exit(1) nearby.

I'm starting to wonder if there's something very weird on my system.  If 
anybody else with IPv6 enabled wants to test this (you can test it from 
the source tree; doesn't need to affect the installed INN), you might for 
example run `authprogs/domain litech.org < foo` where foo is a file 
containing:

    ClientHost: localhost
    ClientIP: ::1
    ClientPort: 119
    LocalIP: ::1
    LocalPort: 119
    .

I can't spend any more time on this today; if anybody has the combination 
of circumstances that would trigger this in practice, I have no problem 
with rolling it back until I can get it working.  Let me know.
