Fyi, I am in contact with Nvidia about problems regarding the floating point special behavior. They are aware of the issue and debating potential solutions, but I don't know if or when we'll see a fixed driver.
Did that go anywhere? I'm inclined to say the optimisation is just invalid, and resolve this as NOTOURBUG.
