        * gimple-ssa-sprintf.c (sprintf_dom_walker::handle_gimple_call):
        Set info.fncode to BUILT_IN_NONE if gimple_call_builtin_p failed.
        Punt if get_user_idx_format succeeds, but idx_format argument is
        not provided or doesn't have pointer type, or if idx_args is above
        number of provided arguments.

        * c-c++-common/pr89566.c: New test.
