I don't see how this example relates. Your C++ example is a real puzzler. Even if `p` were in use during run(), it could still be (and should still be!) free()d before returning from main(). It's a bit tricky but there's potentially LOTS of code that will execute after "`return app.run()`" but before the process exits.

seems like something that optimizer would get rid of.

  No, the static destructors for example cannot be optimized away because their effects are intentional and required. In C++, close braces have potentially limitless implicit code that gets executed.
