Thanks for looking into it. From the trace, my guess
is that FreeBSD always reports that SA_SIGINFO is set
because FreeBSD always passes the relevant info to signal handlers
(at the low level, this doesn't cause problems so it's OK).
Always reporting SA_SIGINFO violates POSIX but I doubt whether
anybody really cares, so does the following patch fix things for you?
It simply adjusts the test so that it doesn't check for this bug.
