Add Version Check to GCC Warning

Or alternatively:

  template <typename T>
  static T deserialize(const std::vector<uint8_t>::const_iterator& backing_start,
                       const std::vector<uint8_t>::const_iterator& backing_end,
                       int offset,
                       int array_offset)
  {
    T v;
    const std::ptrdiff_t total_offset =
        static_cast<std::ptrdiff_t>(offset) +
        (static_cast<std::ptrdiff_t>(array_offset) * sizeof(T));

    if (backing_start > backing_end ||
        backing_end - backing_start < sizeof(v) + total_offset) {
      throw AccessException("Unexpected data type size");
    }

    const uint8_t* src = &*(backing_start + total_offset);
    std::memcpy(&v, src, sizeof(v));

    return v;
  }

Either way is fine with me, thanks
