Hi,
I'm experiencing some problem using LOS with osgOcean. Executing LOS with
osgOcean enabled there are some strange segmentation fault that speak about LOS
intersection visitor and osgOcean main traverse. The traceback isn't the same
at all times, but is something like that:
Code:

Seems to be some side-effect interaction among visitors. Disabling osgOcean the
segmentation fault doesn't appear.
Have you noted a problem like that?
Thank you!
Cheers,
