Summary0013382: vtkXMLUnstructuredGridWriter: corrupted output for polyhedral cells in appended mode
DescriptionThe Graphics\Cxx\TestPolyhedron0.cxx test works in ASCII mode, but comment-out this line and it breaks:

writer->SetDataModeToAscii();

Alternatively, explicitly change it to:

writer->SetDataModeToAppended();

(Binary mode works fine.)

The resulting vtu file has malformed XML. It starts like this:

" offset="588"="1.0"?>
<VTKFile type="UnstructuredGrid" version="0.1" byte_order="LittleEndian" compressor="vtkZLibDataCompressor">
  <UnstructuredGrid>
...etc."

Still an issue in VTK 5.10.0.

An improved test would try all the different data modes (ascii, binary, appended) and compressors (zlib, none).

I am having trouble reproducing this bug. Can you run the test under lldb with Guard Malloc on (env DYLD_INSERT_LIBRARIES=/usr/lib/libgmalloc.dylib)?

This bug was resolved after this request was merged
https://gitlab.kitware.com/vtk/vtk/merge_requests/501 [^]

If you are testing on origin/master that maybe why it is not reproduceable?

Also, see the attached data https://gitlab.kitware.com/vtk/vtk/uploads/5a809cfb40449e6ec58a96028a01906e/grid_only_0_0.zip [^] to have a test case.
