Spoilers: it's this.

ktruss shows absolutely no syscall activity on the authorization
server during the failing test, because Curl's talking to something
else. sockstat confirms that I completely forgot to listen on IPv6 in
the test server. Dual stack sockets only work from the IPv6
direction...

There must be some law of conservation of weirdness, where the
strangest failure modes have the most boring explanations. I'll work
on a fix.

That is also really good to know, though. So that EINVAL message
might, in the end, be completely unrelated to the bug? (Curl doesn't
worry about the error, looks like, just prints it to the debug
stream.)

Thanks!
