Bug#677330: rred crashes in apt-get update
Package: apt
Version: 0.9.6
Followup-For: Bug #677330
I'm not positive that this is the exact same problem, but I'm still
seeing segfaults in rred with apt 0.9.6. I rebuilt rred with debugging
information before my latest crash, and was able to get a full
backtrace. I've attached a file with the short and full backtraces. I've
also saved the core file, the actual rred executable used, and the
contents of my /var/lib/apt/lists from before running "aptitude update";
I've put a tarball of these up here:
<https://cbane.org/rred-segfault.tar.bz2>.
Here's the short backtrace:
