With gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.10)
this gives me the following warning:

Yes. Whichever order I read emacs-devel and emacs-bugs in, itʼs always

You are saying that these lists behave like elementary particles, with
the associated quantum effects?

The more accurately I know what's being discussed on emacs-devel, the
less knowledge I have of the state of emacs-bugs (and vice-versa), so
yes.
