title: View internal std::vector data when debugging in XCode 4
body: <p>On breakpoint XCode shows only aa array of vector members. So I can't view actual std::vector members, such as _M_impl. As I remember, there was this ability in XCode 3.x.</p>
  
  <p>I need this data to set "Watch adress of ..." to check when it will be changed.</p>
