I suspect it's unrelated to getaddrinfo(), but I got some nasty stuff going
on with 2.18 -- many desktop components started segfaulting. I've now dropped
back to 2.17 and things are working again.
From the boot with glibc 2.18 this is the sort of thing journalctl was
showing:

I should have said: this is on a system with 64-bit kernel and
32-bit userspace. I'm seeing something that may be related at
http://www.linuxquestions.org/questions/linux-from-scratch-13/glibc-2-18-and-acroread-4175473288
I last built and installed glibc-2.17 in January, since when
I've updated gcc (4.8.1) and kernel headers (3.10.7). So I
just tried the experiment of rebuilding 2.17 under my current
setup, to check that nothing had gone screwy in the meantime
in regard to my ability to build a properly functioning glibc.
Result: all OK, the system is stable with glibc-2.17 as
rebuilt today. But it's seriously unstable with glibc-2.18 as
built with the same toolchain and configure options, namely:
../glibc-2.17/configure --build=i686-pc-linux-gnu \
--prefix=/usr --with-tls \
--disable-profile --enable-add-ons \
--enable-kernel=3.10.7
