It /is/ undefined behaviour.  (6.2.6.1p5 covers it, though I doubt if
you care.)  It is also common sense.  A _Bool contains either 0 or 1 -
any other value is invalid and can't be achieved without extraordinary
effort designed purely to make bad code.

Yes, you know /exactly/ what is happening with _Bool - write sane code,
and you get the results you expect.  Write code with clear and
intentional errors with the sole intention of getting inconsistent
results, and you get exactly what you expect.
