--- Comment #3 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
We ended up with an empty call_args vec because the pack expanded here:
18842 /* Expand the pack expansion and push each entry onto
18843 CALL_ARGS. */
18844 arg = tsubst_pack_expansion (arg, args, complain,
in_decl);
expanded to an empty vector. So nothing got pushed onto call_args.
