Why is the member "value_" in your Node template a pointer? Maybe you 
forgot to clone this pointer in Nodes copy constructor. This is just a 
guess. You did not post a full compilable example which represents your 
problem, so it is difficult to find the problem. Please post a full 
program.

Also, there is a list template in the C++ Standard Library. Maybe you 
are coding your own list as an exercise, if not you should consider 
whether using std::list is an option.
