I've gotten it down to this:
int getaddrinfo(const char *node, const char *service,
const struct addrinfo *hints,
struct addrinfo **res);
getaddrinfo hates "::1" as a node parameter.
I've attached a tester for getaddrinfo (based on Ulrich Drepper's
http://people.redhat.com/drepper/userapi-ipv6.html )
$> netstat -a -t -p
tcp 0 0 *:www *:*
LISTEN -
tcp6 0 0 *:ssh *:*
LISTEN -
$>./test ::1 ssh
./test: getaddrinfo: Address family for hostname not supported
$> telnet ::1 ssh
Trying ::1...
Connected to ::1.
Escape character is '^]'.
SSH-2.0-OpenSSH_4.3p2 Debian-8ubuntu1
$>./test ::1 www
./test: getaddrinfo: Address family for hostname not supported
$>telnet ::1 www
Trying ::1...
telnet: Unable to connect to remote host: Connection refused
both
$>./test 127.0.0.1 www
and
$>./test 127.0.0.1 ssh
succeed (aka I can talk to the www or ssh daemons running on my system).
If anyone's got a clue, please say so ... I'm kind of in the mists now :)
If not, when I get the time, I'll look into telnet's implementation to
see what they do to accept "::1"

the cause: segmentation fault at:
rv = apr_socket_bind(sock, to);
from static void sendto_receivefrom(abts_case *tc, void *data)
from testsockets.c
the second parameter given is NULL:
apr_socket_bind (sock=0x80d3c78, sa=0x0) at network_io/unix/sockets.c:154
the NULL value comes from
rv = apr_sockaddr_info_get(&to, addr, APR_UNSPEC, 7772, 0, p);
Which was supposed to initialize it, but failed to.
digging deeper we get into network_io/unix/soccaddr.c, where there's a
this call
error = getaddrinfo(hostname, servname, &hints, &ai_list);
This returns -9 which gai_strerror says it means "Address family for
hostname not supported".
getaddrinfo's input params are:
hostname ="::1"
servname = 0x0
hints = {ai_flags = AI_ADDRCONFIG, ai_family = 0,
ai_socktype = 1, ai_protocol = 0, ai_addrlen = 0, ai_addr = 0x0,
ai_canonname = 0x0, ai_next = 0x0}
Will dig deeper, but if somebody has some knowledge why this would
fail, jump in :)
