This error message indicates that your module "SIZES" has been compiled with a
different compiler version than the one you're using to compile fsubs.f90.

Please use the same compiler version for both!

This is not a compiler bug but a user error. I'm closing this PR as invalid.

I agree that the error you quoted is a user error.
This, however, should not happen:

gfortran: Internal error: Aborted (program f951)
Please submit a full bug report.

foo.f90:
      !!! foo.f90 !!!
      module bar
      end module bar
      !!!!!!!!!!!!!!!

toto.f90:
      !!! toto.f90 !!!
      program toto
      use bar
      end program toto
      !!!!!!!!!!!!!!!!


$ gfortran45 foo.f90 -c -o foo.o 
# hand-edit bar.mod and change module version
$ gfortran45 toto.f90
toto.f90:3.13:

      use bar
             1

In other words: no ICE. Just the plain error message.

I guess that the bug reporter uses Windows and runs into PR 47394 (fixed
January 2011 on the 4.5 branch and - back then - on the 4.6 trunk).

Pavel, is this correct? Namely, that you have a gfortran which is older than 21
January 2011 - and that you use Windows? If not, we would be interested in more
details - in particular the output of "gfortran -v" - to trace why there is an
internal error.

The actual message "Wrong module version '5' (expected '4')" is unfortunately
to be expected. Despite trying hard, we have been so far unable to keep the
.mod file format compatible between different GCC minor versions. (At least the
format is stable within releases/release branches.)

Ah, ok. I completely missed that part, sorry.

So I will reopen this PR. However, I think what is missing is a small
self-contained test case.
