Earlier versions of OpenSSH ( < 3.6) had a bug in sshd that sometimes
caused a coredump in the exit path. This had the result of making the
return code passed back to the client random.
Since SunSSH was based on OpenSSH originally, it's possible it still has
this bug. (You can confirm this by enabling core dumps with coreadm on
the server and checking for dumps from sshd).
