dpkg returns Bus Error
Hello everyone,
I have a Debian machine that's mostly woody (just a few packages
from testing like quagga and associated libs) but dpkg seems terminally
broken. Running any dpkg command (except help) results in a Bus Error.
I don't know of any odd occurances (disk/mem failure) that could
be causing this, and the machine (which is a VPN and OSPF router) has
been rock solid.
strace's output as well as a backtrace from gdb are included
below - any help on this would be greatly appreciated; the machine could
use the security patches that just came out.
Thanks for any suggestions!
