Yes, not having any data members in the subclass makes the destructor a no-op. 
  Someone has pointed out that *technically* the behavior is undefined by the 
standard. But in reality what happens is, well, nothing. The empty subclass 
destructor is not called -- so there is no effect.  It works on all C++ 
compilers that I'm aware of.
