Indeed.

   bool is_even(int* valPtr) {
      assert(valPtr != nullptr);
      return *valPtr % 2;
    }
Does not do what you think it does with nullptr. A major game engine [0] has a toggle to enable asserts in shipping builds, mostly for this reason

Let's not vague post on HN. What's the problem with the above?

I'm sorry, but what exactly is the problem with the code? I've been staring at it for quite a while now and still don't see what is counterintuitive about it.

This is a very "Dr Dr it hurts when I do this" "Don't do that" one it must be said.
