Re: tst-getaddrinfo4 failure with glibc-2.18

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

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 \
