The following crashes on writeln, but looks reasonable. Is some form of

struct DateRate {

struct RateCurve {

struct CFS {

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;
    ubyte b;  // <-- ADDED
}
