I confirm what you observed, and that corresponds to what you already told me [some time ago](https://fortran-lang.discourse.group/t/tweeting-fortran/2425/30).  
After your comment I change my code and I am now using a combination of `select rank` and `pack`. Which may not be suitable when performance is critical but does the job for me.
