So does that mean disallowing a structure which contains a union? What about if the final structure is large enough to require passing in memory rather than registers, so that libffi doesn't need to do any clever marshalling, even if some part of the structure wouldn't by itself be able to be passed as an argument in a call? Won't that end up being too restrictive?
