This will naturally be slower than a regular debug or release build, but it is *much* faster than executing your program in [Miri](https://github.com/rust-lang/miri) and still helps find some Undefined Behavior. Unlike Miri, it is fully FFI-compatible (though the code behind the FFI barrier is completely unchecked).
