Key Info: Ubuntu 64 Lucid (No memory issues, no new hardware)

Nearly every application dies with this segfault. Googling around finds dozens of posts that have this exact problem and not a single solution so hopefully you guys can give me a hand.

Example GDB of synaptic:

Starting program: /usr/sbin/synaptic
[Thread debugging using libthread_db enabled]

Program received signal SIGSEGV, Segmentation fault.
0x00007ffff31a1280 in ?? () from /lib/

Did u manage to resolve your problem? I ran into the same problem. – tzippy Jun 25 '13 at 7:52

If you can start aptitude/dpkg, try reinstalling (aptitude reinstall) or rolling back the libc6-i686 package.

Yup, tried to no avail. That is, I successfully reinstalled with apt-get install --reinstall libc6 but it didn't do anything – Shawn Aug 23 '10 at 13:09
Did you tried rolling it back to a previous version? – whitequark Aug 23 '10 at 13:47
Yes, as a matter of fact, it made things quite massively worse. Rolling back libc forces an uninstall of virtually every major package in the system. Est no bueno – Shawn Aug 24 '10 at 4:54
