If either of these are the case (assuming a valid, deterministic,
non-arch-specific implementation) then this violates C's as-if rule.
The compiled version has to act as if it did exactly what the C said.
Optimizations or other transformations that cause the compiled code to
violate this are a bug in the compiler.
