Are "strict aliasing rules" different to the effective type rules of 6.5
p7?  I've never been clear exactly what people mean by "strict"
aliasing.

If I've got the right post, that's an example of UB which remains UB
when the cast is replaced by Rick's union hack.  If the hack has
aliasing issues of its own, they would show in the translation of an
example that is well-defined using casts.
