... but only when you give -funbox-strict-fields, as there, or UNPACK. The point is that it never loses sharing to unbox a strict Int field [1], so it should do that with -O, even without either of the above overrides.
[1] I'm not sure if this is true... if it has to rebox the Int, you get another copy floating around, not the original, right?
