    Problem Text
    This test case fails on platforms which require the grouplist
    argument to -g to contain only session leaders.

    This test uses ps -o to get a list of process ids that are then
    supplied as a space separated list to the ps -g call. ps -o pgid is not
    guaranteed to list only session leaders. Thus the space separated list
    of pids supplied as the grouplist of session leaders may have pids that
    are not session leaders. The XPG4 V2 XCU spec is silent on whether or not
    supplying non-session leader pids to the -g option is an error. Our
    implementation returns 1 and writes a diagnostic message to stderr.

    The testcase needs to allow either behavior.
    Test Output
    ************************************************************************
    /tset/POSIX.upe/ps/ps.ex 1 Failed


    Test Information:
    Assertion #1004 (A): ps -g writes information whose session leaders are
    given in grouplist.
    Expected exit code = 0; Received 1

    Review Response
    XCU Section 1.9 CONSEQUENCES OF ERRORS states

    The many reasons for failure of a utility are
    generally not specified by the utility
    descriptions. Utilities may terminate
    prematurely if they encounter: invalid usage
    of options, arguments or environment
    variables...

    Thus the behavior listed above is not a grey area in the spec.
    Implementaitons may or may not exhibit this behavior.

    We believe not allowing both behaviors is a test suite deficiency
    in the test suite version(s) listed.
