I've run into an issue in which it appears that having more than one
off-screen rendering camera causes OpenSceneGraph to crash, and I was
curious if I'm doing something wrong or if there's a workaround available.
I've got four cameras in the scene graph. Two are fbo cameras for shadow
mapping, two are projective texturing cameras. The two shadow mapping
cameras have ref_ptr's to the same node in the scene, and the two main
cameras have ref_ptr's to the same node (but different from the shadow
mapping cameras.)
The gdb output from attempting to debug the result, and what I get is:
#0 0xb7be86ca in osg::GraphicsContext::releaseContext ()

Any ideas? Thanks in advance,
