[Bug fortran/20151] New: internal compiler error: Bus error

[dir at lanl dot gov]

I have no clue as to what the problem is here, but if I change almost anything
it goes away.

[dranta:~/tests/gfortran] dir% gfortran -c module_plot_hdf.f90
module_plot_hdf.f90: In function 'hdfsds_r8':

Confirmed, thanks for the reduced testcase (and all the other testcases too).
Here is the backtrace:

Reduced testcase:
    module token_module2
      COMMON /MPIPRIV/ MPI_BOTTOM
      integer i
    end module token_module2
    use token_module2, only: mpi_bottom
    use token_module2, only: i
  end
Removing either of the use lines makes the failure disappear.  Note that the
failure happens also without using the ONLY clauses, but I'm not sure if the
code would be illegal then (and wrongly accepted).
