--- Comment #2 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
9351 /* When returning address of a structured binding, if the
structured
9352 binding is not a reference, continue normally, if it is a
9353 reference, recurse on the initializer of the structured
9354 binding. */
9355 tree base = DECL_DECOMP_BASE (whats_returned);
9356 if (TYPE_REF_P (TREE_TYPE (base)))
9357 {
9358 tree init = DECL_INITIAL (base);
9359 return maybe_warn_about_returning_address_of_local (init);
9360 }
init is null here and cp_fold crashes on that.
