* 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.
