When doing multi-threading the smallest little mistake can cause problems, you just have to work through eliminating the possibilities, it can be quite tough. As a general note, OSG-3.4.0 contains quite a few week improvements including on the thread safety side so would recommend using it. The OSG-3.5.0 dev release also uses osgDB::readRefNodeFile() etc. internally to avoid potential issues with mixing the osgDB::Registry Object cache. This improvements might not affect your problem but it might be worth trying to upgrade to at least 3.4.0. With your own code I'd recommend changing from using C* pointers to ref_ptr<> an time you are transferring ownership of the OSG objects, in your code example you pop a pointer to a node off a container, both the container and the local pointer should use ref_ptr<> for memory safety.
