// incorrectly passes the sManager pointer as-is to the bool. This can result in incorrect
// behavior as setConfirmMessage actually checks if the bool is exactly equal to 1, not just
// that it's nonzero.
// Whether the compiler bug occurs or not depends on the exact memory layout of the compiler's
// internal state, and so it's effectively random.
// The kiosk demo version of TWW had the bug occur during compilation, while the three retail
// versions of the game did not have the bug occur.
