This is what "git bisect" ended with. Maybe someone can at least have a look at
this. Feel free to close again if this really doesn't help at all.


$ git bisect bad9eec20bfd5806dd0380e07dbc0f03409ce3d4efb is the first bad
commit

        * emit-rtl.c (set_mem_attributes_minus_bitpos): Remove
        alignment computations and rely on get_object_alignment_1
        for the !TYPE_P case.
        Commonize DECL/COMPONENT_REF handling in the ARRAY_REF path.
