I think the reason why this ICE occurs with my patch
(http://gcc.gnu.org/viewcvs?view=rev&rev=102356) is that my patch enables
data-refs analysis for INDIRECT_REFs. Similar ICE in PR 20256 happens also
before my patch since the data-refs there are ARRAY_REFs, and ARRAY_REFs were
already supported before.
