--- Comment #14 from Alexandre Oliva <aoliva at gcc dot gnu.org> ---
Done, bug 87054.

The patch in comment 13 fails libstdc++-v3; the language-independent
get_object_alignment can't deal with unresolved template expressions, so using
the same logic you added to ivopts to adjust the type of the
compiler-introduced pointer won't do in build_fold_addr_expr_loc.
