--- 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.
