| Test case for assertion #12 of the sigaction system call that verifies |
| signal-catching functions are executed on the alternate stack if the |
| SA_ONSTACK flag is set in the sigaction.sa_flags parameter to the |
| sigaction function call, and an alternate stack has been setup with |
| sigaltstack(). |
| |
| NOTE: This test case does not attempt to verify the proper operation |
| of sigaltstack. |
