Hello,

'D' must be a symmetric matrix 
(https://doc.cgal.org/latest/QP_solver/classCGAL_1_1Quadratic__program__from__iterators.html). 
Thus you matrix D should be

( 2 0.5
( 0.5 1)

and not

(2 0)
(1 1)

That means:

  double  D1[] = { 4.0, 1.0 };
  double  D2[] = { 1.0, 2.0 };

and then you get

  double  D1[] = { 4.0, 1.0 };
  double  D2[] = { 1.0, 2.0 };

Best,
Mael
