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 

[ibook-dhum] f90/bug% gfc -O -Wuninitialized -Wall timing/prandtl_red.f
[ibook-dhum] f90/bug%

I think it is a duplicate of PR27120.
