    Problem Summary PG4U.00112 This was refused because it is a duplicate. Use TSD4U.00023 instead.
    Problem Text
    Passing this test requires that one fail the requirements of sigaction() with
    respect to the sa_flags flag SA_ONSTACK. In XSH4v2, page 545, the following
    requirements are specified for SA_ONSTACK:

    SA_ONSTACK If set and an alternate signal stack has been declared
    with sigaltstack() or sigstack(), the signal will be
    delivered to the calling process on that stack. Otherwise,
    the signal will be delivered on the current stack.

    Concerning TSD4U.00023, we disagree with the consultants response which
    resulted in the change to this test.

    Concerning PG4U.00098, we agree with the submitter of the waiver request.
    That is, the BSD man page which is in direct conflict with the sigaction()
    SA_ONSTACK description is not normative and must not be allowed to override
    the normative requirements stated in XSH4v2. We disagree with the
    consultants initial response stating that the sigstack() semantics as stated
    in BSD are what was intended in XSH4v2. We believe that the spec1170 team
    intentionally fixed a BSD bug and as per the sigaction() requirement, that
    the test should be verifying the alternate stack \fIis\fR in use.
    Test Output
    TEST CASE: sigstack

    TEST PURPOSE #4
    A call to int sigstack(struct sigstack *ss , struct
    sigstack *oss) when the ss_onstack member of ss is
    non-zero shall indicate to the system that the process
    is executing on the specified stack.
    PREP: Call sigstack(ss, oss) with ss_onstack non-zero
    PREP: Call sigaction() with SA_ONSTACK set
    PREP: Send self SIGTERM
    TEST: Verify alternate stack not used
    ERROR: Auto declaration is on the alternate stack and shouldn't be
    Declared Top of Stack = 39c88
    Declared End of Stack = 35c88
    Received Auto Address = 3799f
    4 FAIL
