OCC6.5.3 bug of creating a full sphere

Hi OCC team,

Using new OCC6.5.3, I can't create a full sphere face any more like before.
face = BRepBuilderAPI_MakeFace (gp_Sphere(ax2, radius), 0, 6.2831853071795880, -1.5707963267948970, 1.5707963267948970);
it will throw an exception in another sub API:
static Standard_Boolean IsDegenerated(const Handle(Geom_Curve)& theCurve,
const Standard_Real theMaxTol,
Standard_Real& theActTol)
{
GeomAdaptor_Curve AC(theCurve);
Standard_Real aConfusion = Precision::Confusion();
theActTol = aConfusion;
GeomAbs_CurveType Type = AC.GetType();

if (Type == GeomAbs_Circle) {

//exception throwed here
gp_Circ Circ = AC.Circle();
----------------------------------

Thanks in advance.
