You are not going to like my answer but this may be the 16-byte struct bug. Add something to RateCurve and your code works fine... :-/

struct RateCurve {
  private immutable(DateRate)[] _data;

}


I appreciate and hate the answer :-). I've had a variant of this code working for a while. The previous version had DateRate[] instead of immutable(DateRate)[]. Since DateRate has no immutable aliasing I was trying to go for a more string-like immutable by design class.

My hope is that is not the problem, or if it is it rears its head only in the context of initializers that leave that member empty. In this example if I provided `CFS(1.0, RateCurve([]));` as the initializer then it worked fine.

What exactly is the 16-byte bug? I can't imagine 16-byte structs are generally a problem.

Thanks,
Dan
