Except GCC implements C's unions as allowing to do type punning as an extension and as far as GCC is concerned that is not going to change any time soon. This is a documented exception to the aliasing/type punning rules.
The problem is that this is worse than type punning, because it also allows the preservation of data. Does the extension guarantee that, or would it need a change to at least the documentation? Regards, Nick Maclaren.
