I don't believe that the C++ standard specifies that std::string is
contiguous. From the SGI std::string page (I know it isn't the
standard itself, but its close:
http://www.sgi.com/tech/stl/basic_string.html) they say:

If std::string was guaranteed to be contiguous std::string::operator[]
could be specified as an O(1) operation.

In practise though, most implementations appear to make std::string a
contiguous dynamic array of some sort.
