trace that segfaults

It's a very small demo application: https://github.com/OSVR/OSVR-Tracker-Viewer

If you want to reproduce it for debugging, you don't need any OSVR hardware,
just openscenegraph from git (currently
2a7d72c203104275462a5c0871257383ffbcf6a5) and then starting OSVRTrackerView.

What works:

OSVRTrackerView with openscenegraph 3.4
osgviewer that comes with openscenegraph git master

OSVRTrackerView with openscenegraph git master however segfaults immediately:
