here is the most reduced testcase.
cat > foo1.cc << EOF
template<typename _CharT>     struct basic_string

  struct _Rep   {    _CharT*  _M_refdata() throw()  {  return 0; }        };
  _CharT * dst;
  static _Rep&       _S_empty_rep();
  basic_string()       : dst(_S_empty_rep()._M_refdata())  {  }
};
extern template class basic_string<char>;
struct basic_ostringstream    {
  basic_string<char>  _M_stringbuf;
};
basic_ostringstream foo1;
