Hi Otto
We don't have enough information to solve you problem.
Have you try to debug you application ?
Have you an available callstack to found where you application crash ?
Have you a simple program test which isolate the problem ?
but more simply, is your datasetList array store texture pointer in
osg::ref_ptr ?
Nobody can help you with this too little description.
This probably a misusing of osg code more than a bug in OSG.
