Hi Linh,
I'm guessing that you are using the old osgProducer::Viewer class? Is
this right?
Try moving the addition of the PickHandler to infront of the realize();

Hi,
does anyone know what a Segmentation fault in "std::_List_node_base::hook ()"
means? I was executing these statements:
viewer->setSceneData(scene);
viewer->realize();
viewer->getEventHandlerList().push_front(new PickHandler(viewer)); <<==
Segmentation here
and then:
Program received signal SIGSEGV, Segmentation fault.

Thank you,

PS The exact same code doesn't segmentation fault in one application
but when I link it in another application, it segmentation fault and
I can't figure out what's the difference between them. I know it's
not any memory corruption because it's the first routine executed in
the "main". Thanks.
