        * parser.c (cp_parser_decomposition_declaration): Reject just
        BRACE_ENCLOSED_INITIALIZER_P initializers with nelts != 1 rather
        than all such CONSTRUCTORs, and only if is_direct_init is true.

        * g++.dg/cpp1z/decomp30.C: Add a test for structured binding with
        = {} and = { a, a } initializers.
        * g++.dg/cpp1z/decomp31.C: New test.
