What kind of HEAP problem are you thinking about ?
For HEAP corruptions, the class CString alone used correctly will cause
problems.
For HEAP fragmentation, generic C++ code that uses a lot of allocations
in order to implement the deep-copy semantics of certain C++ objects
may cause heap fragmentation, but that is really up to your application,
and it cannot be foretold in advance.
