--- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
__builtin_clear_padding is intended primarily for C++ which doesn't have these,
I have no plans to support variable length structures in there. So, probably
gimplify_decl_expr should next to clear_padding_type_may_have_padding_p
also check that int_size_in_bytes (strip_array_types (TREE_TYPE (decl))) > 0
(while zero sized types can be handled, there is certainly no padding in them,
so > 0 rather than >= 0).
