[vtkusers] Segmentation Fault

[Andy Cedilnik]

Hi Donna,

Who is Dingrong?

Anyway, the reason why vtkpython works is because when python loads
shared libraries, on some platforms it does not initialize c++ classess
correctly. On platforms such as windows or linux, these classes are
initialized, while on Suns, HPs, SGIs, they are not.

The trick of vtkpython is that it is actually a C++ program which is
linked to python library. Since it is a C++ program, it does initialize
c++ classes.
