In the code from
http://groups.google.fr/group/comp.lang.fortran/browse_thread/thread/120303aae031b672/7dd83bc30a9f19a3#7dd83bc30a9f19a3
gfortran detect the problems coming from the undefined 'j', but not the fact
that 'df4_dxi' is used before it is defined. Am I missing a relevant option
or is it a missing feature/bug in gfortran/gcc?

------- Comment #1 from dominiq at lps dot ens dot fr 2008-03-16 13:46 -------
Reduced test case:
program prandtl meyer
implicit none
integer :: i, j
integer, parameter :: imax = 100
integer, parameter :: jmax = 40
real, dimension(0:jmax,0:imax) :: f1, f1_bar
do i = 0, imax-1
do j = 1, jmax-1
f1_bar(j,i+1) = f1(j,i)
end do
end do
stop
end program prandtl meyer

I think it is a duplicate of PR27120.
