--- Comment #5 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
The PLACEHOLDER_EXPR comes from get_nsdmi
539 if (!in_ctor)
540 {
541 /* Use a PLACEHOLDER_EXPR when we don't have a 'this' parameter to
542 refer to; constexpr evaluation knows what to do with it. */
543 current_class_ref = build0 (PLACEHOLDER_EXPR, DECL_CONTEXT
(member));
544 current_class_ptr = build_address (current_class_ref);
545 }
but no idea how tsubst_copy should handle that.
