[vtk-developers] Examples/Medical3 crash help

Valgrind detected the use of uninitialized variable for Example3:

ref: http://www.cdash.org/CDash/viewDynamicAnalysisFile.php?id=511733


Indeed, Example3 was calling Render() on the vtkRenderer. This is not
a valid call. Only the vtkRenderWindow is allowed to do so. I changed
the comment in vtkRenderer to make it more explicit and commit a fix
to Example3:

cvs commit -m "BUG:Fixed direct call to Render on the vtkRenderer
which is strictly forbidden as the vtkRenderer. Notably, vtkRenderer
relies on values initialized by the vtkRenderWindow. In the case of
Example Medical3.cxx, as Renderer() was called on the vtkRenderer
before any internal initialization of the vtkRenderWindow it resulted
in the use of uninitialized variable. Thanks valgrind for catching
this." VTK/Rendering/vtkRenderer.h
