[ digs around ... ]  It looks like the failure is coming from here:
if (strlen(path) >= sizeof(unp->sun_path))    return EAI_FAIL;

What's the size of the sun_path member of struct sockaddr_un on your
machine?  I count 115 characters in your socket path ... maybe you
just need a less deeply nested test directory.

(If that is the problem, seems like we need to return something
more helpful than EAI_FAIL here.)
