Check the actual pointer which memory was assigned to, not its parent
array pointer.

    services.c:810:14: warning: Assigned value is garbage or undefined [core.uninitialized.Assign]
                                            **r_buf = **new_buf;
                                                    ^ ~~~~~~~~~
