Hi John, I'd guess at an issue of mixing libs and gcc versions. Try removing all the .o and lib and bin directories from your OpenSceneGraph build, also remove the CMakeCache.txt and then try again.
FYI, 2.8.3 really isn't much different to 2.9.x w.r.t how it's built and the Viewer::setSceneData(..) method hasn't been touch pretty well for the whole history of the osgViewer library so certainly won't be the cause of the error.
