(Ignoring an distracting irrelevant hominem remark.) If you think that "What time is a three story building?" must have a correct answer, you are wrong. Similarly, if you think that HHH can simulate itself correctly, you are wrong. int H(ptr p, ptr i); int main() { return H(main, 0); } You showed that H returns, but that the simulation thinks it does not return. DDD is making it unnecessarily complex, but has the same problem.
