Yes, I mean user definite classes.
When I create geometry class
//////////////////////////////////////////////
    dGeomClass c;
    c.bytes = sizeof (dxCylinder);
    c.collider = &dMyClassColliderFn;
    c.aabb = &dMyClassAABB;
    c.aabb_test = 0;
    c.dtor = 0;
    dMyClass=dCreateGeomClass (&c);

//////////////////////////////////////////
static dColliderFn * dMyClassColliderFn (int num)
{
  if (num == dBoxClass) return (dColliderFn *) &dCollideMyClassBox;
  if (num == dSphereClass) return (dColliderFn *) &dCollideMyClasSphere;
  if (num == dMyClass) return (dColliderFn *)&dCollideMyClassMyClass;
  if (num == dPlaneClass) return (dColliderFn *) &dCollideMyClassPlane;
  return 0;
}

dMyClassColliderFn do not return     dCollideMyClassMyClass in
dCreateGeomClass because  dMyClass is not set until it return and
dCollideMyClassMyClass do not set in colliders array.

It is not a bug but I do not know how to set collider for  MyClass -
MyClass collision.
