Problem is alignment.

I believe that this was fixed on trunk by the following change:

2009-12-17  Richard Guenther  <rguenther@suse.de>

        PR middle-end/42397
        * builtins.c (get_object_alignment): Properly deal with
        a CONST_DECL base.
        * expr.c (emit_block_move_hints): Assert the alignment makes sense.
