   Thank you all for your replies. I am sorry that the information was   
   incomplete. The function widen does allocate memory for the returned   
   string.   
      
   I have wrapped the array in an object in RAII fashion. One thing that   
   bothers me is a subtle interaction between the constructor and   
   destructor to ensure the right delete calls when an exception is   
   thrown. My first draft would free garbage pointers.   
      
   I know std::vector provides the memory layout guarantee needed in this   
   case. But if I put raw pointers into the vector, I still need to   
   free them explicitly. I could wrap them into a moveable object   
   that owns the string, but isn't this what std::unique_ptr is?   
      
   I also got a pointer to boost::ptr_vector. If I can convince it to use   
   delete [] on its pointers..
