[Bug fortran/24527] New: derived types not displayed correctly

This may be a gdb bug, but anyway...

 cat type.f90
program main
  type foo
    real :: a
    integer :: b
  end type foo
  type(foo) :: q
  q = foo(3.14, 42)
  print *,q
end program main
$ gfortran -g type.f90
$ gdb ./a.out

Confirmed.  This is a gdb bug as if I do:
"set lang c"
it works.

Oh, I think there is a dup around somewhere too.

------- Comment #2 from woodzltc at sources dot redhat dot com  2005-10-28 04:39 -------
Yes. I agree that it is more like a gdb bug.  But I would rather say that it is
an enhancement request for gdb, because GDB never says that it supports
complete Fortran-95 syntax.  The support for Fortrn 77 is also not deemed as
complete.  

I coded a patch in gdb for that.  The link is
http://sourceware.org/ml/gdb-patches/2005-10/msg00208.html

The patch in http://sourceware.org/ml/gdb-patches/2005-11/msg00217.html
implements this quite nicely AFAICT.  I'll try and take care of the rest.

This works with the patch I mentioned in comment #3.  That patch is in the GDB
source tree since 2006-02-24, so this is "fixed" in GDB 6.5.  On the GCC side
we seem to do the right thing for scalar components.  For array components
obviously we don't but there is a separate bug about that.

So I'm calling this FIXED.
