While we're talking about odd issues that only seem to happen on Okapi,

[ 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.)
Looks like it was. Good catch. What's the best way to fix?
Note that this problem was triggered by having a buildfarm buildroot
path of length about 49 or 50. I'm lucky not to have triggered it
myself. Do I need to add a check to limit the buildroot path length?
cheers
