    Problem Text
    This test may fail because it assumes that the SIGSEGV signal will
    create a core file.

    Per the <signal.h> section of the specificaton, page 795, the
    default action for SIGSEGV is (iii), which is:

    "Abnormal termination of the process.

    Additionally, implementation-dependent abnormal termination
    actions, such as creation of a core file, may occur"

    The key word is MAY, creation of a core file is NOT REQUIRED by
    the specification.

    Our implementation does not generate a core file as a result of
    a SIGSEGV signal, and therefore correctly puts CLD_KILLED (102) into
    si_code, rather than CLD_DUMPED (103).

    (Note that this TSD is independent of the ERROR: si_status incorrect
    problem also observed in the above journal file.)
    Test Output
    SPEC1170TESTSUITE CASE 27
    After a call to int sigaction(int sig, const struct
    sigaction *act, struct sigaction *oact) with
    SA_SIGINFO set in the sa_flags member of the sigaction
    structure pointed to by act and sig equal to SIGCHLD,
    on entry to the signal catching function specified by
    the sa_handler member when the child terminated
    abnormally the si_code member of the structure pointed
    to by the siginfo argument shall contain CLD_DUMPED,
    the si_pid member shall contain the child process ID,
    the si_status member shall contain the child's
    signal, the si_uid member shall contain the
    real user ID of the process that sent the signal and a
    core file shall be present.
    PREP: Set up action for SIGCHLD
    PREP: fork() a child that dumps itself
    PREP: generate SIGSEGV from child
    TEST: signal = SIGCHLD
    TEST: si_code = CLD_DUMPED
    ERROR: si_code incorrect. Expected 103,Received 102
    TEST: si_status = SIGSEGV
    ERROR: si_status incorrect. Expected SIGSEGV,Received Unknown signal (124)
    TEST: Core file is present
    ERROR: Core file was not generated
    FAIL
