        Backport from trunk
        PR libgfortran/80727
        * transfer.c (read_sf_internal): Remove bogus code to detect EOR.
        (read_block_form): For internal units, generate EOR if no more
        bytes left in unit and we are trying to read with ADVANCE='NO'.

        * gfortran.dg/read_3.f90: New test.
