--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
This is because the prefetch pass calls prepare_gimple_addressable while
already in SSA form and that for obvious reasons requires !allow_ssa, because
we want a temporary decl that can be made addressable. So the assert added in
the gimplification to SSA changes makes no sense in that case, unfortunately it
doesn't know that internal_get_tmp_var has been called with !allow_ssa.
