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

program main
  implicit none
  integer, parameter :: n=5
  character(len=6), dimension(n,n) :: a
  character(len=6), dimension(n) :: r1
  integer :: i
  logical, dimension(n,n) :: mask

  write (unit=a,fmt='(I6.6)') (i*i+200-17*i,i=1,n*n)
  mask = .true.
  forall (i=1:n)
     mask(i,i) = .false.
  end forall

  r1 = maxval(a, dim=1, mask=mask)

end program main
