Fix issue of getting pointer from std::vector of size 0

C++11 introduced the `std::vector::data()` method. In addition to being
more syntatically pleasing, it should correctly handle the condition
when the `std::vector` is size 0 and therefore has no real pointer.
(Expressions like `&v[0]` are undefined when the `vector` is empty.)
