    Problem Text

    This test may fail on implementations because the wrong OTIME value is
    being checked.

    This test is attempting to verify the proper contents of the OTIME
    field for the sem2_ID semaphore set (semaphore 35 in the test).
    However, due to an error in the code, the wrong value is being
    checked.

    The code sets the sem2_OTIME correctly the first time, but then
    improperly assigns the value to sem_OTIME rather than sem2_OTIME when
    it attempts to remove any leading zero from the output. The following
    code shows the error.

    sem_OTIME="no-entry"
    sem_CTIME="$(date '+%H:%M:[0-9][0-9]')"
    # remove a possible leading zero
    sem_CTIME=${sem_CTIME#0}
    ...
    sem2_OTIME="$(date '+%H:%M:[0-9][0-9]')"
    # remove a possible leading zero
    sem2_OTIME=${sem_OTIME#0}
    sem2_CTIME="$sem2_OTIME"

    Note that sem_CTIME in the previous semaphore set removes the leading
    zero properly. Even though sem2_CTIME is also set incorrectly,
    sem2_CTIME is never used, so it is of no consequence in the other tests.

    As a result of this error, "no-entry" is being checked rather than the
    proper time expression, and the test fails.

    Specifically, in the ipcs_startup() function, in the sem2_ID section,
    change the assignment from

    sem2_OTIME=${sem_OTIME#0}
    to
    sem2_OTIME=${sem2_OTIME#0}

    Review Response
    It is true that there is a fault in this test, however the test output
    also shows that the implementation is not compliant. The requirements
    for output of the ipcs command were amended in corrigendum U032 (March
    1998). On systems which correctly implement the amended specification
    this test fails differently. The failure is covered by PIN4C.00045.

    It is recommended that this request is refused.
