Summary0030754: Coding - the array of weights should begin with Lower, not the constant value 1 within Geom_BSplineCurve.cxx
Descriptionstatic Standard_Boolean Rational(const TColStd_Array1OfReal& W);

this function in Geom2d_BSplineCurve.cxx and Geom_BSplineCurve.cxx, use the constant value 1 as the lower index, but the variable W could use other value as the lower index, for example 0. If use 0, the function Rational() maybe overflow.
Additional information
and documentation updates		static Standard_Boolean Rational(const TColStd_Array1OfReal& W)
{
  Standard_Integer i, n = W.Length();
  Standard_Boolean rat = Standard_False;
  for (i = 1; i < n; i++) {
    rat = Abs(W(i) - W(i+1)) > gp::Resolution();
    if (rat) break;
  }
  return rat;
}

Please check the code above, the variable i should begin form W.Lower();
