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.
See <http://gcc.gnu.org/bugs.html> for instructions.
Finished compiling fsubs
gfortran: fsubs.o: No such file or directory
Completed call to gfcompile.bat
No nonmem execution.






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.
