--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> 2011-04-12 12:30:54 UTC --- Yeah, cxx_eval_array_reference doesn't expect to have sizeof (x) > 1 accesses to STRING_CSTs. Unfortunately, fold_read_from_constant_string doesn't handle those either, and as for C++0x I fear it must always succeed, it will need to handle all the endianity fun.
