    Problem Text
    The above failure is the result of improperly initialize the
    the first element of the queue. in SRC/common/vsthlib/vsth_cpi.c
    the following code is found:

    first.next = (struct qe *) NULL;




    first.last = (struct qe *) NULL;

    (void) insque((void *) &first, (void *) &second);

    The XPG5 XSH spec on page 403 states the following:

    "If the queue is to be used as a circular list, the application must
    initialize the forward and backward pointer of the initial element of
    the queue to the element's own address"

    In this test "second" is the first element of the list and it is not
    initialized.

    Changing the two lines above to the following should fix the problem:

    second.next = &second ;
    second.last = &second ;
