[Bug fortran/29060] New: spread causes ICE in gfc_trans_array_constructor

["keinstein_junior at gmx dot net" <gcc-bugzilla at gcc dot gnu dot org>]

Hi,

I got AN ICE trying to compile 

----------
module bcc
   implicit none
   private
   type md_field
       real,dimension(:,:),pointer :: position
   end type md_field
   real,dimension(1:3,1:2),parameter :: unitcell &
         = reshape((/ 0.25,0.25,0.25, 0.75,0.75,0.75 /),(/3,2/))
contains

   subroutine createBccLattice(x,counts)
      integer,dimension(1:3),intent(in) :: counts
      type(md_field),pointer :: x
      integer :: i,j,k

      do i=1,counts(1)
          do j=1,counts(2)
              do k=1,counts(3)

                  x % position(:,1:2)&
                        = unitcell + spread((/ i,j,k/),2,size(unitcell,2))
              end do
          end do
      end do

      return
   end subroutine createBccLattice


end module bcc
----------

maybe it is related to some other spread related errors, I encountered in an
older gfortran debian package, which seemed to occure only after several spread
calls. Unfortunately at that time it was too difficult to get a nice code
snippet for the report.
