Basically, you need garbage collection.


You can either roll your own (using a pool based allocator/collector
as the moderator suggests, or perhaps some C++ smart-pointer scheme
that does reference counting), or use a bolt-on garbage collector
such as the Boehm-Demers-Weiser conservative collector for C.
