Which one, how did you modify it, and how did you compile it?

That usually comes from trying to construct a point:
Point_d p(1,1,1,0);
This does not construct a 4D point of coordinates 1, 1, 1 and 0 but a 3D 
point with infinite coordinates. You need to use iterators to construct a 
point of dimension >=4.
