It looks to me that node is out-of-bounds, and you dereference a 0 pointer. Check that node is not bigger or equal to nv.size(). > Is there a better way of getting the AGLContext object out of > Equalizer? I'm working with how eqHello creates things, and I noticed > that configVisitor goes about it a bit differently. Where are you doing this? Why do you need the AGLContext there? In general, it is quite dangerous to play around with GL context's in places and threads, unless you're sure of what you are doing. Normally it's less painful to move this stuff, e.g., to Window::configInitGL. The ConfigVisitor/accept follows the Visitor pattern. Google can explain it better then me.
