OK, I've reproduced this one too. Here's what I did (Colin, this may
provide some hints for your case too): I stuck "exit 1" at the bottom
of the "fail" function in then ran:

$ env TEST_SSH_LOGFILE=/tmp/sshd.log SUDO=sudo make tests LTESTS=connect-privsep

and in /tmp/sshd.log I found:
ssh_sandbox_child: setrlimit(RLIMIT_NOFILE, { 0, 0 }): Invalid
argument [preauth]

so, setrlimit is the problem, but only for
UsePrivilegeSeparation=sandbox.  Not sure why though (or, for that
matter, why the test in configure didn't catch it).

    Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
