The issue is that you're starting with a Node_Type of some sort, which is present in the record. GNAT won't let me do anything to compute the start of the record (actually computing it is ok, but won't let me use the record based upon that address). This is so messed up, that I've decided to abandon any semblance of this idea. Lucky for me, I can use a lookup array to do what I need efficiently.
