It is a known gotcha in the C++ Standard.  From the two viable
constructors that could be selected by overload resolution,
vector<InputIterator=int>(int, int) (if I can abuse template syntax to
explicitly specify the constructor template arguments) is preferred
over vector(unsigned, const int&), because the first is an exact
match, while the second involves integral promotion for the first
argument.

  template <class InputIterator>
    vector(InputIterator first, InputIterator last);

  explicit vector(size_type n, const T& value);
