Re: ldconfig issue with raspbian, may affect debian too

That's not the one to look for. You want:
Tag_ABI_VFP_args: VFP registers
which is also set there. "readelf -h" also says
Flags: 0x5000002, has entry point, Version5 EABI
What does "ldconfig -p" say for you on problematic system?
Sorry It seems when I pasted the stuff from irc (while trimming
unrelated stuf) I missed the most important line

Which says

The issue appears to be related to ld.so cache regeneration during
upgrade. It didn't happen for me when I took a slightly older raspberry
pi foundation image and updated it to the latest version but I was able
to reproduce it by doing.
wget
http://snapshot.raspbian.org/201302200144/raspbian/pool/main/e/eglibc/libc-bin_2.13-37+rpi1_armhf.deb
dpkg -i libc-bin_2.13-37+rpi1_armhf.deb
rm /var/cache/ldconfig/aux-cache
rm /etc/ld.so.cache
ldconfig
apt-get -f install (which upgrades libc-bin back to 2.13-38)
Once a system is suffering from the issue it is nessacery to remove
/var/cache/ldconfig/aux-cache and run ldconfig. Removing only
/etc/ld.so.cache and running ldconfig is not sufficient.
Based on that it seems the soloution is to make libc.preinst remove
/var/cache/ldconfig/aux-cache as well as /etc/ld.so.cache and bump the
version that triggers the removals. Do others agree?
