[Bug libfortran/14872] New: [gfortran] Variables used for REC= in READ / WRITE always case run-time error

[bdavis9659 at comcast dot net]

This problem is from FM410.FOR and FM413.FOR of the NIST tests.


! demonstrates using a variable for REC in READ/WRITE
       implicit none
       integer i,j,irec
       OPEN(UNIT=10,ACCESS='DIRECT',RECL=80)
       DO I=1,10
          WRITE(UNIT=10,REC=i)i
       END DO
       STOP
       END

$ gfortran y.f
$ ./a.out
At line 6 of file y.f
Fortran runtime error: Record number must be positive


from g77:

$ g77 y.f
$ ./a.out


GNU Fortran 95 (GCC 3.5-tree-ssa 20040405 (merged 20040331))

from y.f.t03.original:

        _gfortran_filename = "y.f";
        _gfortran_line = 6;
        _gfortran_ioparm.unit = 10;
        _gfortran_ioparm.rec = &i;
                            ^^^^^^^^^
                      wrong, run time lib expects a value

        _gfortran_st_write ();
        _gfortran_transfer_integer (&i, 4);
        _gfortran_st_write_done ();
        i = i + 1;

so this looks like a front end issue.  note that direct access reads/writes work
fine with a constant REC, like: 

WRITE(10,REC=100)
