| * This test ensures that ensures that FORTIFY's run-time bits aren't enabled with ASAN on. Most |
| * ways of getting FORTIFY to break turn into UB unless you get creative. Rather than remaking the |
| * entire FORTIFY test-suite with this added constraint, we pick a function with well-defined |
| * behavior when a FORTIFY check would fail (umask), and hope that the success of that is indicative |
| * of the rest working. |
