Sorry I had a typo in my example, but we did in fact place the const cast
on the reference, not on the pointer. That is what silences the warning:

return const_cast<typename
remove_reference<T>::type&>(*static_cast<volatile typename

(I had the '*' in the wrong place last time)

Anyways, I'll try out the abort variation. I do like that much more.
