But doesn't this error happens during instantiation as the error message indicates? If definition of Node::FooNode is commented out, the templates themselves are accepted. Also, if the nested classes are un-nested out of Node, the code compiles w/out errors too. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43135
