对基于堆栈的分配器的任何建议？(除了建议使用私人/公共成员的课程)

struct Heap
{
    void* heap_start;
    void* heap_end;
    size_t max_end;

    Heap(size_t size)
    {
        heap_start = malloc(size);
        heap_end = heap_start;
        max_end = size + (size_t) heap_start;
    }

    ~Heap()
    {
        ::free(heap_start);
    }

    void* allocate(size_t bytes)
    {

        size_t new_end = ((size_t) heap_end) + bytes;

        if( new_end > max_end )
            throw std::bad_alloc();

        void* output = heap_end;
        heap_end = (void*) new_end;
        return output;
    }

}
