Oh, and whoever designed the strict aliasing specs: To me they seem widely impractical. The fact that there's essentially no way to explicitly alias, without memcpy'ing, is just absurd. The standard's language is also so cryptic, that well versed people (like Regehr you linked to) can't agree with each other what the exact requirements are. The union aliasing trick isn't, to my knowledge, actually precisely standards conforming.
