Besides, re: 'fixing with the side-effect of a different thing': I think the alignment caused by using an union is not actually a side effect of it but an intended effect of it, as the compiler must ensure correct alignment of each union member -- on architectures where alignment of 32-bit ints is unnecessary, the union will not cause undue alignment, whereas the __aligned__ attribute would.
