What's the oldest GCC version you're targeting? Modern GCC has std::unique_ptr (zero-overhead pointer wrapper with RAII semantics), std::shared_ptr and std::make_shared (avoiding a separate allocation using operator new). This should work after some adjustments, as long as your data structures are acyclic. You just have to avoid taking short-cuts to optimize things, using references and plain pointers instead of the std:: wrappers. In this regard, Boehm GC is hard to beat.
