[vtkusers] Help with crashes in VTK

Tue Sep 6 14:28:05 EDT 2011

I see in some cases, references to vtkSmartPointer's are passed to functions.  probably not a good idea.

1. When the pipeline created in the stack is detroyed, it detroys the output object within the pipeline.  By returning a vtkSmartPointer may be a remedy to this (in which case calling Register(0) is a bug), but I'm not sure without checking the document.  I tend not to use vtkSmartPointer in straight C++ code since smart pointer tend to complicate things up and clutters the code.
2. Unpredictable failures tend to be thread related, or to a less extend, lack of memory.  You mentioned that the crash does not occur in the threaded code.  But it is worthwhile to double check.

Thanks for the response, I was just wondering1.  What this is trying to accomplish?2.  If this would explain the behavior that I'm seeing (where it fails unpredictably)?

        case eOrientation_XZ:            marching->SetImageRange(extent[0], extent[1], slice, slice, extent[4], extent[5]);            break;        case eOrientation_YZ:            marching->SetImageRange(slice, slice, extent[2], extent[3], extent[4], extent[5]);
            break;    }    marching->SetValue(0, 0.5);
    vtkSmartPointer<vtkStripper> stripper = vtkSmartPointer<vtkStripper>::New();    stripper->SetInputConnection(marching->GetOutputPort());
    stripper->Update();
    return stripper->GetOutput(); // Crash occurs here as update is called (I'm not sure why it's not on the previous line)}

Add the following before returning: vtkSmartPointer<vtkPolyData> poly = stripper->GetOutput();poly->Register(0);return poly; See if that helps.

Actually, allow me to clarify this.Qt is 4.7.2 as downloaded from their Qt SDK
vtk, gdcm, and my program are all compiled as Release with Debug info

Yes, everything is in release.
