--- Comment #1 from Reid Kleckner <rnk at google.com> ---
It is our general policy that optimizations should not emit warnings, so even
though the optimizer sees undef, Clang will not emit warnings. That would make
your build success dependent on optimization level, which is widely considered
to be a Bad Thing.
Note that gcc -O0 does not find this bug either.
