Comment:

 This manner of implementing assignment operator is not a bug. It's
 described in Sutter and Alexandrescu's
 [http://www.gotw.ca/publications/c++cs.htm C++ Coding Standards] and more
 briefly on the
 [http://en.wikipedia.org/wiki/Assignment_operator_%28C%2B%2B%29

 Wikipedia].

 BTW, your patch is invalid: it'd rule out assignment from a const object.
