[Insight-users] Global smartpointers.

[dominique at toepfer-web.de]

Hi everyone,

I have a question concerning global smartpointers. 

When porting some code that still used VTK 4.x to VTK 5.6.1, our application crashed on exit. We found some global vtk objects (now using smartpointers) to be responsible for that.

It does not seem to be a bug in our code: I took the cone example form http://www.vtk.org/Wiki/VTK/Examples/Cxx and made all smartpointers global. The application still works as expected but crashes on exit. 

Of course, we can avoid global smartpointers in our application, but now we are curious about the explanation of this behavior. Can anybody explain this?

I attached the code and the call stack. We used Visual C++ 2008.

Thanks in advance!
Dominique
