[vtkusers] Help with crashes in VTK

Here is code snippets for every crash I have mentioned.  Again, any insight
would be helpful.

Crash 1:
bool BinaryDifference::computeDifference(vtkSmartPointer<vtkImageData>
image1, vtkSmartPointer<vtkImageData> image2) {
    bool hasDifference = false;
    int* extent = image1->GetExtent();
    int x, y, z;
    char *image1Ptr, *image2Ptr;
    //can't do a straight-up pointer walk; there's probably some padding
    //on the end of the array in X that shouldn't be directly accessed.
    //so, instead, get the scalar pointer at each row.  Seems to be
reasonably quick still.
    for (z = extent[4]; z <= extent[5]; ++z) {
        for (y = extent[2]; y <= extent[3]; ++y) {
            image1Ptr = (char*)image1->GetScalarPointer(0, y, z);
            image2Ptr = (char*)image2->GetScalarPointer(0, y, z);
            for (x = extent[0]; x <= extent[1]; ++x, ++image1Ptr,
++image2Ptr) {
                if (*image1Ptr != *image2Ptr) {
                    QVector<int> pt(3);
                    pt[0] = x;
                    pt[1] = y;
                    pt[2] = z;
                    differentPoints.push_back(pt);
                    hasDifference = true;
                }
            }
        }
    }
    return hasDifference;  // Crash occurs on this line, as vtkSmartPointer
gets removed from the heap
}


Crash 2:
// Organ is a QString, currentActors is a QSet of vtkSmartPointer<vtkActor>,
removedOrgans is a QSet of QString
if (organ.isNull())
        return;
    if (currentActors.contains(organ)) {
        mRenderer->RemoveActor(currentActors[organ]);
        currentActors.remove(organ);
    }
    removedOrgans.insert(organ); // Crash occurs on this line, as
vtkSmartPointer gets removed from the heap (not sure why it's not on the
previous line)

Crash 3:
vtkSmartPointer<vtkPolyData>
vtkPipelines::getContoursAtSlice(vtkSmartPointer<vtkImageData> const
&binaryImage, int const slice, EOrientation const inOrientation) {
    int* extent = binaryImage->GetExtent();

    vtkSmartPointer<vtkMarchingSquares> marching =
vtkSmartPointer<vtkMarchingSquares>::New();
    marching->SetInput(binaryImage);
    switch (inOrientation) {
        case eOrientation_XY:
            marching->SetImageRange(extent[0], extent[1], extent[2],
extent[3], slice, slice);
            break;
        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)
}

Crash 4:  Occurs at the same place as Crash 3 except the stack trace is
different

Crash 5: Occurs on the line marching->SetInput(binaryImage); of Crash 3.

Crash 6:
void PatientData::setImageBeforeUndo(vtkSmartPointer<vtkImageData> image) {
    previousUndoImage->DeepCopy(image);
}  // Crash occurs here as vtkSmartPointer is removed from the heap

Crash 7: Occurs at the same place as Crash 3 except stack trace is
different.

Please let me know if you'd like any more information.
