I don't see such a line.

I do:
...
(res = {{1, +, 1}_1, +, 1}_2))
(get_loop_exit_condition
if (j_3 == pretmp.57_24))
/opt/gcc/gcc-4.3-work/gcc/testsuite/gfortran.dg/vect/vect-5.f90:14: note: Alignment of access forced using versioning.
/opt/gcc/gcc-4.3-work/gcc/testsuite/gfortran.dg/vect/vect-5.f90:14: note: Vectorizing an unaligned access.(analyze_scalar_evolution
(loop_nb = 2)
(scalar = j_3)
(get_scalar_evolution
(scalar = j_3)
(scalar_evolution = {i_1, +, 1}_2))
(set_scalar_evolution
(scalar = j_3)
(scalar_evolution = {i_1, +, 1}_2))
)
..
Do you need more?
