Description Thomas Koenig 2005-06-22 11:35:44 UTC
Another corner case of eoshift that's not correct...
in eoshift3, this time.

$ cat eoshift.f90
program main
  implicit none
  integer, dimension (3,3) :: a, b, w
  integer, dimension (3) :: bo, sh
  integer :: i,j

  a = reshape((/(i,i=1,9)/),shape(a))
  sh = (/ 3, -1, -3 /)
  bo = (/-999, -99, -9 /)
  b = eoshift(a, shift=sh, boundary=bo)
  w = reshape((/ -999, -999, -999, -99, 4, 5, -9, -9, -9 /), shape(b))
  do j=1,3
    do i=1,3
      if (w(i,j) /= b(i,j)) print *,i,j,w(i,j),b(i,j)
    end do
  end do
end program main
$ gfortran eoshift.f90
$ ./a.out
           1           2         -99 -1644167172

Proposed patch.

The patch was for the wrong bug report *sigh*.

Actually, the patch should be the other way around.
