DSGraph::getScalarMap returns a reference to the map, so this cannot be
null.  Do you mean that all of the "entries" in the map are null?  If so,
remember that DSGraphs are built in the context of some function (as
indicated by hasFunction/getFunction), so only scalars in that context
will be in the map...
