[Bug fortran/17760] New: Internal compiler error for assignment to array of derived type

["dr dot johan at gmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

This is on an Athlon w/ 2GB RAM, Redhat9 (kernel 2.4.20-20.9).

$ /home/johan/gcc-test/bin/gfortran -v

$ /home/johan/gcc-test/bin/gfortran -c bug.f90
bug.f90: In function 'find_surfaces':
bug.f90:13: internal compiler error: Segmentation fault

--- begin bug.f90 ---
module seplib
  integer, parameter :: r8 = selected_real_kind(15, 307)
  type :: R_type
     real(r8), dimension(:), pointer :: coord
  end type R_type
  type :: geom_type
     type(R_type), dimension(:), pointer :: R
  end type geom_type
contains
  subroutine find_surfaces(geom)
    type(geom_type), intent(inout) :: geom
! Here's the offending line:
    geom%R(1)%coord(1) = 0.0
  end subroutine find_surfaces
end module seplib
--- end b.f90 ---

This is real code that was maximally trimmed down to still trigger the bug.

I've been tracking gfortran in the gcc main branch since the merger of tree-ssa.
Impressive progress guys! I think gfortran is very nearly there.

Thanks, Johan
