--- Comment #3 from anlauf at gcc dot gnu.org ---
Reduced testcase:

program p
  implicit none
  integer, parameter :: nbmode = 3
  integer :: k
  real:: mass(nbmode*2)
  do k = 1, nbmode*2
 mass(k) = k
  end do
  print *, (mass(k+k), k=1,nbmode)
end program

Also valgrind shows that bad things happen with -ffrontend-optimize ...

Workaround: use -fno-frontend-optimize.
