[vtkusers] CellEdgeNeighbors of UnstructuredGrid

[dce06003]

Hello all.

I am trying to determine which cells share an edge with a specified
cell of my unstructured grid, composed with voxels.

I adapted this example from the VTK Wiki:

http://www.paraview.org/Wiki/VTK/Examples/Cxx/PolyData/CellEdgeNeighbors

changing the triangleFilter->GetOutput() with my unstructured grid.

When I run it, I got the following error on function
GetCellNeighbors():

"Microsoft C++ exception: std::bad_alloc at memory location"



Is there anyone who got the GetCellNeighbors() working with an
unstructured grid? 
Can someone please help?

Thank you very much,
