[arch-general] ldconfig -> Aborted.

[C Anthony Risinger]

this might be a bit brief as it's really late and i'm already in
trouble :-/ ... will expand as needed.

i upgrade my machines and VMs very regularly, at least once a week,
this last batch of updates broke all of my VMs in particular ...
hardware devices still seem to function correctly.  they are not
really broken, but i am unable to regenerate `/etc/ld.so.cache` on any
of them (3 ATM).

upgraded packages (in order, from pacman.log):

augeas
linux-api-headers
glibc <---------------------- prime suspect!!!!
binutils
fakeroot
gcc-libs
gcc
pcre
git
keyutils
krb5
libmysqlclient
polkit
yajl
libvirt
module-init-tools
mkinitcpio
linux
pm-quirks
postgresql-libs
shadow
systemd-arch-units
texinfo

... during the upgrade i saw:

upgraded linux-api-headers (3.0.1-1 -> 3.1.4-1)
/tmp/alpm_gfNxsS/.INSTALL: line 4:   575 Aborted
sbin/ldconfig -r .
Generating locales...
en_US.UTF-8...cannot map archive header: Invalid argument
upgraded glibc (2.14.1-1 -> 2.14.1-2)
upgraded binutils (2.21.1-2 -> 2.22-2)
/tmp/alpm_dwiY8r/.INSTALL: line 5:   654 Aborted
sbin/ldconfig -r .
upgraded fakeroot (1.18.1-1 -> 1.18.2-1)

... the locale stuff is just a side effect of the ldconfig failure
IIRC -- locales are a little borked because the archive file was blown
away, not a problem tho.  for some reason ldconfig refuses to update
on all the VMs (each has worked without issue until today, for several
months):

# ldconfig
Aborted

... i tried blacklisting some virtio modules (balloon in particular)
and tripling memory, no change, and not convinced its 100% related to
virtio yet.  i tried removing `/var/cache/ldconfig/aux-cache` to force
ldconfig to rescan everything (vs. stat checks) -- again, works on
hardware but not VM.  i tried removing the last library it processes
before failing (per strace), no change, it just fails on another
(libgcrypt -> libsysfs).  i tried reinstalling glibc and whatnot ...

these VMs are all pure 64bit, no multilib, and pure systemd, original
initscript stuff purged.  the only thing i didnt try was downgrading,
because i would have to use the ARM ... i use 9p2000.L passthru for
the rootfs of each VM, bindmount a local mirror into each VM's VFS,
then configure pacman to use the `pool` directory of the bound mirror
as a cachedir -- the net effect is pacman never downloads anything,
ever, because it believes it already has :-)  slightly odd perhaps,
but working well for quite some time.

any ideas?  i can't find anything out of place, or any significant
differences, and i'm not sure what to try next -- nothing unusual in
dmesg or logs, on the VMs or the host.  host is completely current as
of Dec 14 00:00 CST.  reduce strace follows, limited to files and
signals.  thanks for your time so far, if you made it to this point
legitimately :-)
