[vtkusers] vtkLookupTable crashes in release mode. VTK8.1.1

Order of operations matter. This works well:

Hi,

I am having issues creating a vtkLookupTable. I am encountering a peculiar issue with lookup tables when in release mode. Whenever I am trying to SetHueRange (or SaturationRange or ValueRange) I run into an access violation. But this works as expected in debug mode. Any one run into the same issue? Any help will be greatly appreciated.

Example Code:
  vtkSmartPointer<vtkLookupTable> bwLut = vtkSmartPointer<vtkLookupTable>::New();
  bwLut->SetHueRange (0, 0);
  bwLut->SetSaturationRange (0, 0);
  bwLut->SetValueRange (0, 1);
  bwLut->Build();
  bwLut->SetTableRange (0, 255);
