<p>In my ongoing quest to get a filter to process multiple time steps worth of data into a single result field I've attempted to derive a C++ vtk filter from
<span>vtkMultiTimeStepAlgorithm</span>. However, the attached simple example segfaults out when I try to apply it in paraview. All it should do is a shallow copy of input to output for now. I don't have much luck getting a stacktrace from paraview but it
appears to be bombing at:</p>

<p>Can someone please help or point me to a minimal working example of a <span>vtkMultiTimeStepAlgorithm</span> filter?</p>
