--- Comment #5 from Harald Anlauf <anlauf at gmx dot de> ---
This looks pretty much like a namespace problem.

Adding in the example in comment #4

    common /x/ integer_kinds

e.g. to subroutine sub1 makes the code illegal but compile.
It then prints:

           1           2           4           8
           0           0           0           0

I have looked at use_iso_fortran_env_module in module.c, but
frankly I do not understand how the code is supposed to work.
