Which is very odd -- both functions are supposed to update the name server etc in the same way, I think?

Basically, I have an instance of Emacs 27 =E2=80=94 rev. aea1b4db72 =E2=80= =94 a head of emacs-27 from about two weeks ago, which, have been running f= or that time, is failing to resolve any remote hostname synchronously (whic= h, for instance, Gnus normally does), while asynchronous requests (as in = =E2=80=98url-retrieve=E2=80=99) are still working fine. A newly started instance of the same Emacs does not demonstrate the issue. = And alas, despite being almost convinced, that I had already met this prob= lem before, I cannot say how exactly to reproduce it. However, I suppose, the fact, that this is by no means a pristine configura= tion is not much relevant, since the error goes down to C sources, namely t= o =E2=80=98make-network-process=E2=80=99: (make-network-process :name " *net-test*" :buffer (get-buffer-create " *net-test*") :host "gnu.org" :service 80 :nowait nil) ;; Debugger entered--Lisp error: (error "gnu.org/80 Name or service not kn= own") More specifically, a call to getaddrinfo() in =E2=80=98network_lookup_addre= ss_info_1=E2=80=99 returns EAI_NONAME. Could it be a problem in GNU Emacs, or have I broken my system somehow? =2D-=20 In GNU Emacs 27.0.91 (build 2, x86_64-pc-linux-gnu) of 2020-04-30 built on nora Repository revision: aea1b4db72df92595a3f642d18bf57254d74772b Repository branch: emacs-27-nightly System Description: Debian GNU/Linux 10 (buster) Configured using: 'configure --with-x-toolkit=3Dno' Configured features: XPM JPEG TIFF GIF PNG RSVG SOUND GPM DBUS GSETTINGS GLIB NOTIFY INOTIFY ACL= LIBSELINUX GNUTLS LIBXML2 FREETYPE HARFBUZZ M17N_FLT LIBOTF XFT ZLIB OLDXM= ENU X11 XDBE XIM MODULES THREADS LIBSYSTEMD PDUMPER LCMS2 GMP --=-=-= Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iIMEARYIACsWIQRSX35grYEsI2F1K7TIsPhUjufz5wUCXrvrHA0cZGFnQGdudWku b3JnAAoJEMiw+FSO5/PnsgYBAISzaCFDQDSdIMaOPAPpvQEKOrKjM84tdH0d1pWM ehiRAP9ha64nUuN1DCIkf9TLbqYM2STRtIqxud2A7S6mHWNTBA== =tRwe -----END PGP SIGNATURE----- --=-=-=--
