--- Comment #27 from Jerry DeLisle <jvdelisle at gcc dot gnu.org> ---
With the patch applied and the following test case:
MODULE m
IMPLICIT NONE
TYPE :: t
integer :: j
CHARACTER :: c
integer :: k
CONTAINS
PROCEDURE :: write_formatted
GENERIC :: WRITE(FORMATTED) => write_formatted
PROCEDURE :: read_formatted
GENERIC :: READ(FORMATTED) => read_formatted
END TYPE
CONTAINS
SUBROUTINE write_formatted(dtv, unit, iotype, v_list, iostat, iomsg)
CLASS(t), INTENT(IN) :: dtv
INTEGER, INTENT(IN) :: unit
CHARACTER(*), INTENT(IN) :: iotype
INTEGER, INTENT(IN) :: v_list(:)
INTEGER, INTENT(OUT) :: iostat
CHARACTER(*), INTENT(INOUT) :: iomsg
WRITE (unit, "(i10,3x,A,3x,i10)", IOSTAT=iostat, IOMSG=iomsg) dtv%j, dtv%c,
dtv%k
END SUBROUTINE
SUBROUTINE read_formatted(dtv, unit, iotype, v_list, iostat, iomsg)
CLASS(t), INTENT(INOUT) :: dtv
INTEGER, INTENT(IN) :: unit
CHARACTER(*), INTENT(IN) :: iotype
INTEGER, INTENT(IN) :: v_list(:)
INTEGER, INTENT(OUT) :: iostat
CHARACTER(*), INTENT(INOUT) :: iomsg
READ (unit, "(i10,3x,A,3x,i10)", IOSTAT=iostat, IOMSG=iomsg) dtv%j, dtv%c,
dtv%k
END SUBROUTINE read_formatted
END MODULE
PROGRAM p
USE m
IMPLICIT NONE
class(t), allocatable :: x
NAMELIST /nml/ x
x = t(55,'a',42)
WRITE (10, nml)
REWIND(10)
READ(10, nml)
END
On the write I see what I expect, but we need to adjust list_read.c to handle
the parsing of input correctly.
$ ./a.out
At line 42 of file 1test.f03 (unit = 10, file = 'fort.10')
Fortran runtime error: namelist read: misplaced = sign
$ cat fort.10
