Summary0010528: vtkXMLUnstructuredGridWriter segfault
DescriptionSee the attached Python script which loads a polydata .vtp file containing only points and associated scalar arrays. The polydata gets clipped and then saved to a .vtu file, but a segfault occurs.
Steps To ReproduceSave both files in the sample place, run bug.py
Additional Informationvtk 5.4.2

I tried it in c++ and got the same segfault.

Here is the code to reproduce in c++:

#include <vtkSmartPointer.h>
#include <vtkClipDataSet.h>
#include <vtkBox.h>
#include <vtkPolyData.h>
#include <vtkXMLPolyDataReader.h>
#include <vtkXMLUnstructuredGridWriter.h>
#include <vtkUnstructuredGrid.h>

int main (int argc, char *argv[])
{
  vtkSmartPointer<vtkXMLPolyDataReader> dr =
      vtkSmartPointer<vtkXMLPolyDataReader>::New();
  dr->SetFileName("doh.vtp");
  dr->Update();
  
  vtkSmartPointer<vtkBox> box =
      vtkSmartPointer<vtkBox>::New();
  box->SetBounds(0, 0.65, -0.982, 0.984, -1.03, -0.302);
  
  vtkSmartPointer<vtkClipDataSet> clip =
      vtkSmartPointer<vtkClipDataSet>::New();
  clip->SetInputConnection(dr->GetOutputPort());
  clip->SetClipFunction(box);
  clip->Update();
    
  vtkUnstructuredGrid* ug = clip->GetOutput();
  cout << ug->GetNumberOfPoints() << endl;
  
  vtkSmartPointer<vtkXMLUnstructuredGridWriter> dw =
      vtkSmartPointer<vtkXMLUnstructuredGridWriter>::New();
  dw->SetInputConnection(clip->GetOutputPort());
  dw->SetDataModeToAscii();
  dw->SetFileName("doh.vtu");
  dw->Write();

  
  return EXIT_SUCCESS;
}


If you comment
  dw->SetDataModeToAscii();

it does not segfault.
