I can't reproduce this.  My testcase returns -1 and ENOMSG just fine.
I also inspected the message queue related source code which is basically
the same running on FreeBSD.  I don't see how it should be able to
return something other than -1 in this case.  If you're still sure there's
a bug somewhere, please provide a reproducible, minimal testcase.
