The best thing to do is to use stty to disable ^O if you plan to use the binding. Bash doesn't modify terminal settings.

(And there's no difference between the readline library used with bash and the standalone library. That's how bash can be built against the standalone library if desired.)

As discussed in the pkgsrc-users mailing list (see http://mail-index.netbsd.org/pkgsrc-users/2018/01/16/msg026141.html ), the Control-O key binding doesn't work for me on NetBSD.

It seems that the cause is that the flush / VDISCARD character, which is by default Control-O, is not disabled in the readline library as used within bash.

With the attached patch it works for me. I might have overlooked some locations more where a similar change is necessary, depending on configuration; the change effective for me is

+#if defined (VDISCARD)
+  tiop->c_cc[VDISCARD] = _POSIX_VDISABLE;
+#endif
+
