        PR libgfortran/83191
        * io/transfer.c (list_formatted_read_scalar): Do not set
        namelist_mode bit here. (namelist_read): Likewise.
        (data_transfer_init): Clear the mode bit here.
        (finalize_transfer): Do set the mode bit just before any calls
        to namelist_read or namelist_write. It can now be referred to
        in complex_write.
        ^ io/write.c (write_complex): Suppress the leading blanks when
        namelist_mode bit is not set to 1.

        * gfortran.dg/namelist_95.f90: New test.
