trace that segfaults
It's a very small demo application: <a href="https://github.com/OSVR/OSVR-Tracker-Viewer">https://github.com/OSVR/OSVR-Tracker-Viewer</a>
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:
