@edhartnett @AlexanderRichert-NOAA FYI

[edwardhartnett]

OK, let me take a look at these...

[edwardhartnett]

I cannot reproduce these.

What version of gfortran is being used here?

[climbfuji]

As the issue says in the title and description, clang@14. Scrap that. This is gfortran 9.4 together with clang@10 (not 14 as I mentioned earlier)
