re PR middle-end/35043 (ICE in tree-data-ref because signed_type_for_types returns NULL)
2008-02-04 Richard Guenther <rguenther@suse.de>
PR middle-end/35043
* gimplify.c (gimplify_init_ctor_eval): Convert array indices
to TYPE_DOMAINs base type instead of using bitsizetype here.
* gcc.c-torture/compile/pr35043.c: New testcase.
