I noticed that you included a modified form
of my list example.  It is not equivalent.  Because you are not
setting front in insert(), the test if(front.get() == 0) will always
be true.  As a result the list will always have size 1 which defeats the
purpose of the test. The original crashes on msvc 9.0.
