I'm not sure if it's possible to prove things about programs of unbounded
complexity, but your example is wrong. Dead code does not raise the
complexity of the program at all. In fact, the applicable definition of
complexity here is the number of bits which the shortest functionally
equivalent program requires.

But the informational complexity altogether can't exceed M.
