--- Comment #1 from Robin Dapp <rdapp at gcc dot gnu.org> ---
Confirmed, smaller example:

program main
  implicit none
  integer, parameter :: n=3D5
  character(len=3D6), dimension(n,n) :: a
  character(len=3D6), dimension(n) :: r1
  integer :: i
  logical, dimension(n,n) :: mask

  write (unit=3Da,fmt=3D'(I6.6)') (i*i+200-17*i,i=3D1,n*n)
  mask =3D .true.
  forall (i=3D1:n)
     mask(i,i) =3D .false.
  end forall

  r1 =3D maxval(a, dim=3D1, mask=3Dmask)

end program main
