[lldb-dev] [PATCH] std::vector::data()

[Greg Clayton]

>From the header documentation in the stl_vector.h from our C++ library on Mac OS X:

      /**
       *   Returns a pointer such that [data(), data() + size()) is a valid
       *   range.  For a non-empty %vector, data() == &front().
       */
      pointer
      data()
      { return pointer(this->_M_impl._M_start); }

So it does state "For a non-empty %vector, data() == &front().", so I would avoid this patch for now.
