How do I map my struct to mem avoiding surprise:

I guess this is bad again, as for the very same reasons of unspecified behaviour, true? At least I cannot use a static_cast instead of (foo&) cast.
Altough I am not terribly skilled in standards interpretation I think the following should be safe: union { mem[]; foo s; }; Now I should be able to access this as mem[0], mem[1], ... from the writing side, e.g. from a function that fills my buffer, and later access it with s.a, s.b. I would be glad if someone more skilled than me could assert my believe. Roland aka speedsnail
