<pre>"clang --help" outputs concerning -fsanitize:
-fsanitize=<check> Enable runtime instrumentation for bug detection:
address (memory errors) | thread (race detection) | undefined (miscellaneous
undefined behavior)
Only 3 arguments are mentioned and documented, so that one has the impression
that these are the only ones supported. But there is also at least
float-divide-by-zero (<a class="bz_bug_link

title="RESOLVED FIXED - floating point division by 0.0 vs -ftrapv vs IEEE floating point semantics"
href="show_bug.cgi?id=11854#c3">bug 11854 comment 3</a>).
Tested with Debian's clang-3.4 1:3.4.1-2 package.</pre>
