--- Comment #1 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
Confirmed from 4.5 to 4.9 (trunk). Compiling the following reduced tests
program energy
implicit none ! all dble
integer(kind=4)::ns ! size of spatial lattice
integer(kind=4)::i,j,k,l
integer(kind=4),allocatable::back(:,:) ! works up to 20,10
integer(kind=4)::di,index
doubleprecision,allocatable::sumffi(:)
doubleprecision,allocatable::f(:,:,:,:) ! the dimensionless field
go to 123
do di = 0, ns/2
sumffi(di) = sumffi(di) + f(i,j,k,l)*f(back(i,di),j,k,l)
end do
123
contains
function T(i,j,k,l,iu,ju,ku,lu,id,jd,kd,ld) ! only what depends on ijkl
doubleprecision::T
integer(kind=4)::i,j,k,l,iu,id,ju,jd,ku,kd,lu,ld
T = f(i,j,k,l)*( f(i,j,k,l) - f(iu,j,k,l) - f(id,j,k,l) )
end function T
end program energy
gives and ICE with 4.5, the error

Reduced test giving an ICE with a clean trunk (r209224)
program energy
implicit none ! all dble
integer(kind=4)::ns ! size of spatial lattice
integer(kind=4)::nt ! size of temporal lattice; nt >= ns
integer(kind=4)::i,j,k,l!,iu,id,ju,jd,ku,kd,lu,ld
integer(kind=4),allocatable::back(:,:) ! works up to 20,10
integer(kind=4)::di
doubleprecision,allocatable::sumffi(:)
doubleprecision,allocatable::f(:,:,:,:) ! the dimensionless field
! potential energy; first something I did in an earlier paper
nt = 10
ns = 2
allocate( f(nt,ns,ns,ns), back(ns,0:10) )
allocate( sumffi(0:nt/2))
go to 123
do di = 0, ns/2
sumffi(di) = sumffi(di) + f(i,j,k,l)*f(back(i,di),j,k,l)
end do
123
contains
function T(i,j,k,l,iu,ju,ku,lu,id,jd,kd,ld) ! only what depends on ijkl
doubleprecision::T
integer(kind=4)::i,j,k,l,iu,id,ju,jd,ku,kd,lu,ld
T = f(i,j,k,l)*( f(i,j,k,l) - f(iu,j,k,l) - f(id,j,k,l) )
end function T
end program energy

reduced a bit further.
program energy
go to 123
123
contains
function T(i,j,k,l,iu,ju,ku,lu,id,jd,kd,ld)
end function T
end program energy
the label is "123"
make it "123 "
and the segfault does not happen.
(random strange thing seen when reducing it)
