--------------------+------------------------------
 In `get_local_listener` which is used by `tor_ersatz_socketpair`,
 `sin6_family` is currently being set to `AF_INET` in the IPv6 case when
 `AF_INET6` should be used instead.

 This code was introduced in commit
 9b24609af003cb79091e628c179cf617ff41aae7 from this past August, so this is
 not a brand-new problem.

 I tested this on my OpenBSD box by forcing an IPv6 socket to be used for
 `tor_ersatz_socketpair` and running the test suite.  There is a test in
 the test suite that tests `tor_ersatz_socketpair`: it (of course) fails
 using the current `AF_INET` code but it passes when using `AF_INET6`
 instead.

 PR to follow to change `AF_INET` to `AF_INET6` in the IPv6 case.
