Reported by Clive Page, http://gcc.gnu.org/ml/fortran/2009-01/msg00335.html
Fails with gfortran 4.1, 4.2, 4.3 and 4.4, but works with NAG f95, g95, ifort
(9.1, 11.0), openf95.
The proper result of the test program is:
------------------------------------------
normal
1 2 3 4
10 20 30 40
100 200 300 400
y-inverted
100 200 300 400 <<<<<<< These lines
10 20 30 40 <<<<<<< are missing
1 2 3 4 <<<<<<< with gfortran
------------------------------------------
The program:
!-----------------------------------------
module testy_mod
implicit none
contains
subroutine mysub(text, array)
character(len=*), intent(in) :: text
integer, intent(in) :: array(:,:)
integer :: j
print *, text
do j = 1, ubound(array,2)
print '(10000i4)', array(:,j)
end do
end subroutine mysub
end module testy_mod
program testy
use testy_mod
implicit none
integer, parameter :: nx = 4, ny = 3
integer :: array(nx,ny)
data array / 1,2,3,4, 10,20,30,40, 100,200,300,400 /
call mysub('normal', array)
call mysub('y-inverted', array(:,ny:1:-1))
end program

This is the same as PR38852 and the fix for that one works for this too.
