Hi, my code will has a different result when use -qopenmp with ifort. But I haven't add any openmp parallel zone, it should just run as serial. What could cause this error? Any suggestion is appreciated, thank you!

There is not enough information here to give any suggestions other that to try the current release of ifort. It's 2021.12.0. It was released a few weeks ago.
If you still have a problem, please post a small reproducer.

-qopenmp implies -auto. If you have any code that relies on variables being implicitly saved that is likely to break if you use -qopenmp.
