I just finished fixing another issue and am now looking at this one. Generally
speaking if code worked before under g77, we do our best to have it work under
gfortran with -std=gnu which is the default, then if something violates f95 or
later we will give error with -std=f95. I will post back here what I determine
as far as what the bug specifically is.
