        * io/list_read.c (nml_get_obj_data): Delete code which calls the
        child read procedure. (nml_read_obj): Insert the code which
        calls the child procedure. Don't need to touch nodes if using
        dtio since parent will not be traversing the components.

        PR libgfortran/78670
        * gfortran.dg/dtio_25.f90: Use 'a1' format when trying to read
        a character of length 1. Update test for success.
        * gfortran.dg/dtio_28.f03: New test.
        * gfortran.dg/dtio_4.f90: Update to open test file with status =
        'scratch' to delete the file when done.
