    I reported Bug#301912, consisting of repeated perl warnings and
    segfaults during package installation. It seems to have been
    reported before, but I wasn't sure, and if so it's an old bug,
    so I filed it as a new bugreport as a bebconf bug. I've hit the
    same bug several times since, and now think it's it's more likely
    to be a dpkg or apt bug. I'm not sure how to proceed from here.
    I'm using debian testing and downgrading doesn't seem to be an
    option. I'm am inclined at this point to refile the bug as belonging
    to dpkg, in hopes of a resolution to get my system stable again.

    As noted in the bug report, my system is a 486 with 100% stock debian
    sarge. Although my system is old it has run apt and debconf since
    these packages were introduced, and never failed before running dpkg.
    It's been upgraded from every version of debian since Buz, which may
    be the problem, since dist upgrades were not well supported in the
    early days. Due to the slowness of the box, however, doing a clean
    reinstall now would be a major undertaking, with unsure prospects of
    resolving this bug.

    I've made some recent hardware upgrades on the system, but if it's
    a hardware bug this is it's only symptom so far, which seems unlikely.

    In addition to the information in Bug#301912 I have the following
    new information, part of which I sent to the debconf maintainer.
    Based on the new information, besides suspecting a different package,
    I now believe the bug is intermittent and could be related to
    system load, possibly swapping-related. There's even a slight chance
    it's kernel related (I'll have to test for that). Note the last install
    operation posted below succeeds by simply repeating an apt-get command
    and letting it run alone by abstaining from further interaction with the
    system, while the installation is running.

    A side concern here is that the base debian packages are outgrowing
    old, slow systems. I hope that's not the case. Besides this failure,
    from a practical standpoint running dselect, for example, is becoming
    infeasible on my 30MB 486 (100MHz) because it's so slow.

    Here's my latest results which can be appended to Bug#301912:
