| Test case for assertion #12 of the sigaction system call that verifies |

| SA_ONSTACK flag is set in the sigaction.sa_flags parameter to the |
| sigaction function call, but a new stack has not be set by sigaltstack(). |
| |
| NOTE: This test case does not attempt to verify the proper operation |
| of sigaltstack. |
