vect dump ends with:

/home/seb/ex/pr25371.c:26: note: Access function of PHI: {0, +,
1}_4(get_loop_exit_condition 
  if (i_99 < D.1700_228) goto <L54>; else goto <L55>;)

/home/seb/ex/pr25371.c:26: note: === vec_transform_loop ===
/home/seb/ex/pr25371.c:26: note: === vect_do_peeling_for_alignment ===

and the problem seems to come from the fact that in
vect_create_addr_base_for_vector_ref, we're calling 
base_offset = force_gimple_operand (base_offset, &new_stmt, false, dest);  
with a base_offset that contains a chrec:
((num_tD.1607 *) (long unsigned intD.4) {0, +, nD.1614_23}_4 * 16B);
