I tried it with the attached file and the build.sh but calling gfortran
directly w/o mpif90 wrapper.

That's with --enable-checking=3Dyes,extra,rtl and:
mainline: 4d66685e49d20e0c7a87c5fa0757c7eb63ffcdaa (Fri Mar 5 05:25:54 2021
-0800)
GCC 10: c85c24099b28f7af907466af2c1b73da9455368c (Fri Mar 5 12:45:41 2021
+0100)

That's on x86_64-gnu-linux (Ubuntu 14.04.4 LTS).

It did compile without any problems; I also tried running it with valgrind =
and
did not spot anything there, either.

Looking at the Elk webpage, also no gfortran-related issues are reported
threre.=
