In the hope of saving a little time tracking these down, the problem looks like
it is in the return statement for the relevant _compare(...) methods for each of
those types in phobos/std/typeinfo/ti_<type>.d.

For example, in phobos/std/typeinfo/ti_double.d:

|   static int _compare(double d1, double d2)
|   {
|   if (d1 !<>= d2)     // if either are NaN
|   {
|       if (isnan(d1))
|       {   if (isnan(d2))
|           return 0;
|       return -1;
|       }
|       return 1;
|   }
|//  return (d1 < d2) ? -1 : 1; // <-- problem here
|   return (d1 < d2) ? -1 : (d1 > d2) ? 1 : 0;
|   }
