[vtkusers] why VTK works in Debug mode, but not in release mode?

[Cesar Rabak]

This positivelly indicates a problem with memory
access. It remains to be proved if it stems from a
users' program or from the VTK kernel itself:

1) Windows compilers normally disable some (if not
all) optimizations;

2) in debug mode the memory layout of the application
becomes different which can bring more 'real state'
where a 'wild pointer' could deference w/o causing a
GPF.
