[vtkusers] Problem with vtk and purify

[ursula.goette at philips.com]

Dear all,

I am using VTK and try to purify my code in which I use the vtkDataSetReader or one
of the more specific readers to read in data. On an Update() call or on GetOutput() I get
the message from the purifyer that I am freeing mismatched memory. The purifyer always
points to the vtkIO.dll and that the error comes from a free call.

Does anyone know how this can happen?? I cannot remove this error myself.

Thanks
Ursula
