Geometry-related objects are registered into global object stores. I believe materials, logical volumes, physical volumes, solids and regions are all deleted when their stores are destroyed. This happens when Geant4 itself is shutting down. Unless you have a need to reset the geometry and therefore clear the stores during a session, you should consider these objects to be "owned" by Geant4 once they are initialized using new. In effect, the memory is permanently allocated until your application ends. I don't believe this is problemmatic, as you will generally only load one geometry during a given session. You may cause some serious problems if you delete some of these objects before the application ends, e.g. deleting materials or regions could invalidate a number of pointers in Geant4 data structures. --Jeremy
