--- Comment #2 from Jan Hubicka <hubicka at gcc dot gnu.org> --- It is most likely some problem with computing bit offsets for the alias oracle. I guess multiplying that number by sizeof (long) * 11 * 11 * 8 triggers overflow. Probably harmless for -fdisable-checking generated code since that access should be undefined behaviour then. I will take a look.
