@ndkeen I have fixed the issue #5539. It is due to an obsolete use of IF block with the most recently fortran compilers. No answer change occurred. Please test.
@bishtgautam please review.

I can verify this fix does allow the test to run.

To fix this you must be updating the submodule for betr. Please mention which hash of betr is being used now in the PR description above.

With mention of changes to betr submodule, would it be possible for someone to make a change to the maint-1.0 branch in betr? I have copy of the file that needs to be replaced -- it's solely to get around issues discovered building with GCC version 10 and higher.
