If you select the View > Block Status command, TotalView will also give you additional information about memory when it is displaying structured or raw data. For example, you are told if the memory is in a text, data, or bss section. (If you see unknown, you are probably seeing a stack variable.)

If you have enabled the Memory Debugger, this additional information includes letting you know if memory is allocated or deallocated or being used by a guard block or hoarded.
