Bug#270147: "Segmentation faulty tree" (#270147) still present in Lenny, broken /var/cache/apt/*.bin available for download

found 270147

I occasionally ran into this bug on Lenny, can't remember on which
platform, but never deterministically.

But today I reproducibly ran into this bug with both, apt-get and
aptitude. Independent of what I did: aptitude; aptitude -u; aptitude
upgrade; apt-get upgrade, I always get the "Segmentation faulty
tree... 50%" ("Building dependency tree... 50%^MSegmentation fault").

Moving /var/lib/apt/extended_states away didn't help.

Couldn't even do an apt-get install gdb for generating a backtrace.

Moving away pkgcache.bin and srcpkgcache.bin from /var/cache/apt/
finally did help (thanks to waldi for that hint), but copying them
back after upgrading two packages didn't reproduce the segfault --
they always got recreated.

So I installed gdb and can provide a backtrace the next time it

But for now I can just offer those two package cache dbs (about 9 MB
each) which caused the segfault in case anyone's still interested in.
They are available for download at
