Garbage Collection Pitfall in C++ but not in D?

Like their C++11 counterparts:

	void declare_reachable(void* p);	// the region of memory 
starting at p
						// (and allocated by some allocator
						// operation which remembers its size)
						// must not be collected
	template<class T> T* undeclare_reachable(T* p);

	void declare_no_pointers(char* p, size_t n);	   // p[0..n] holds 
no pointers
	void undeclare_no_pointers(char* p, size_t n);
