    Problem Text
    A MSF is requested because the implementation does not return 0
    on a successful call to getcontext.

    The current implementation returns the traditional additional return value
    of 100 to indicate a special non-error condition. Since current programming
    recomendations advocate checking for error situations (i.e. checking for -1
    in this case), this does not affect portable applications.
    Test Output
    TEST CASE: getcontext

    TEST PURPOSE #6
    When the context returned from a call to
    int getcontext(ucontext_t *ucp) is passed to
    setcontext() the program execution shall continue as
    if the corresponding getcontext() call had just
    returned.
    PREP: Setup alternate signal stack
    PREP: Handle SIGALRM signals on normal stack
    PREP: Handle SIGUSR1 signals on alternate stack
    PREP: Handle SIGUSR2 signals on normal stack
    PREP: Get current context
    TEST: Execution continues with getcontext after setcontext
    ERROR: getcontext returned 100
    6 UNRESOLVED

    Review Recommendation No Resolution Given
    Review Response
    A temporary waiver for a minor system fault is recommended.

    This is an issue with applications which check for a 0 return value
    to indicate success. These applications will compile but not run
    properly. However, a reasonable QA process should catch the problems
    this causes. Once the failure is detected changing the code to work
    properly should be simple and straightforward (but bothersome).
