Package: aptitude
Version: 0.4.11.11-1+b2
Severity: grave
Justification: renders package unusable


For over a month now (presumably since the last aptitude upgrade on testing)
I have been seeing segfaults recorded in /var/log/messages on two i386 boxes
and on an amd64, all running testing.

I have not reported earlier because I hoped to get some useful info using gdb.
My first attempts with gdb have failed to catch the segfault whether using
aptitude, aptitude-dbg or directly attaching to the cdrom process spawned by 
aptitude.

1) An entry in /var/log/messages:

Oct  2 10:48:44 conquest3 kernel: cdrom[4987]: segfault at 200 ip b807b71d sp bf
a34890 error 4 in ld-2.9.so[b8068000+1c000]
Oct  2 10:48:56 conquest3 kernel: cdrom[5028]: segfault at 200 ip b7ff871d sp bf
cee290 error 4 in ld-2.9.so[b7fe5000+1c000]
Oct  2 10:56:42 conquest3 kernel: cdrom[5031]: segfault at 200 ip b7f9571d sp bf
8e9850 error 4 in ld-2.9.so[b7f82000+1c000]
Oct  2 10:56:49 conquest3 kernel: cdrom[5033]: segfault at 200 ip b806971d sp bf
a96ac0 error 4 in ld-2.9.so[b8056000+1c000]

2) These are written somewhere around when aptitude prompts for a DVD & one is 
inserted as in

Media Change: Please insert the disc labeled 'Debian GNU/Linux testing _Squeeze_ - Official Snapshot i386 DVD Binary-1 20090921-05:51' in the drive '/dvd/' and press [Enter].

3) aptitude will typically read many of the files from the dvd correctly, but
then report an error on at least one of the package files.

4) Obviously I have checked the DVDs and associated hardware. In any case
it is happening on several machines with different drives and media.

The best I have managed with gdb so far is this sort of thing:-

which is not much help.
