[vtkusers] Valgrind complains when using vtkSmartPointer, depending on which object is created

[Bill Lorensen]

I just compiled and ran your program with valgrind.
No leaks at all.

What OS are your running? What compiler version? What version of VTK?

we run valgrind every night on vtk's test suite. We do have to pro dive
suppressions for some rendering false alarms. But your simple program does
not need and suppressions.
