I think I've reduced this down to a simple testcase:

class mytest
{
public:
  mytest( const mytest & );
  mytest();
  ~mytest();

  mytest &operator+=(const mytest& str);

};

inline const mytest operator+( const mytest &s1, const mytest &s2 )
{
    mytest tmp( s1 );
    tmp += s2;
    return tmp;
}

int main()
{
  mytest a;
  mytest b;

  mytest c = a + b;
  return 0;
}

[jss@localhost jss]$ g++ -O mytest.cc
mytest.cc: In function `int main()':
mytest.cc:14: internal compiler error: tree check: expected class 'd', have 'r'
   (indirect_ref) in genrtl_cleanup_stmt, at c-semantics.c:760
