[Boost-users] Pointer "boundary checker" class or tools?

Hello: I a new to C++. Have not use it yet. For a long time I was wondering if there is a way to automatically check if pointer has creep out of its "known area of access" in memory. Obviously such tool to check pointer would be really slow or too slow for release codes since we want to check pointer location at each pointer access, read or write. Is there such a tool or class to do Pointer "boundary checker" during debug? Thanks. HP
