--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
This is because we have a SCEV like
{(integer(kind=4)) {0, +, {1, +, 1}_1}_1, + 1}_2
which is affine and passes all other tests in scev_analyzable_p. But we really
need to have all SCEVs that pass this test pass get_rename_from_scev which
means we should be able to call chrec_apply on it.
I have a patch.
