------- Comment #7 from pinskia at gcc dot gnu dot org  2006-10-23 06:47 -------
Reduced testcase:
struct string
{
    struct _Rep{}; static _Rep _S_empty_rep_storage[];
    void *_M_rep () const{} void _M_destroy () throw ();
    ~string ()
    {
        _Rep  *a = (_Rep *)((void *)(&_S_empty_rep_storage));
        if (__builtin_expect (_M_rep ()!= a, false)) _M_destroy ();
    }
};
struct ios_base { virtual ~ ios_base (); }; struct ostream : virtual
ios_base{};
struct stringbuf 
{
    int t()const; string _M_string;
    string str () const
    {
      string __ret;
      if (t()) return __ret;
    }
};
struct ostringstream : ostream { ostream   __ostream_type;  stringbuf
_M_stringbuf; };
void sizeString ()
{
  ostringstream s;
 s._M_stringbuf.str ();
}
