May be extend this test-case a little bit and avoid compiler optimizations
because the test-case just sets sockaddr_in6 fields... for example create
a socket and try bind() with sin6?

int sd = SAFE_SOCKET(AF_INET6, SOCK_STREAM, 0);
bind(sd, (struct sockaddr *)&sin6, sizeof(sin6));
SAFE_CLOSE(sd);

Thanks,
Alexey
