version * Delete ai list objects in ~ATC/AIMgr.cxx:AIMgr::~AIMgr() * Delete colors in GUI/new_gui.cxx: NewGui::~NewGui.cxx * Delete memory allocated to the class member "route" in Instrumentation/gps.cxx * Delete all globals (except a few "unsafe" ones that still cause segfaults and need further examination. * Use an SGShared pointer for navaid memory allocation, so that pointers to individual navaid objects can be included safely in multiple navaid lists
