Package: libapt-pkg4.12
Version: 0.9.12
Severity: normal
File: /usr/lib/i386-linux-gnu/libapt-pkg.so.4.12
Hi *,
I am getting a reproducible segmentation fault in
/usr/lib/i386-linux-gnu/libapt-pkg.so.4.12 in
pkgDPkgPM::ProcessDpkgStatusLine.
I first got a segfault today on one machine, but did not capture any
more information on this, since a second start of apt-get did not
produce the same crash.
But now in my workstation this is happening as well an every single time
I start "apt-get dist-upgrade" again. It happens also on every machine
where the package "cpuid=20130610-2" is installed and msr-tools=1.3-1 are
upgraded or newly installed.
Those two packages have a file conflict /usr/share/man/man1/cpuid.1.gz,
which prompts dpkg to output
dpkg: error processing /var/cache/apt/archives/msr-tools_1.3-1_i386.deb (--unpack):
trying to overwrite '/usr/share/man/man1/cpuid.1.gz', which is also in package cpuid 20130610-2
which seemingly triggers the segmentation fault.
The line from the kernel log is
[ 3954.102323] apt-get[14525]: segfault at fffffff4 ip 00000000f768036b sp 00000000ffa8bd20 error 5 in libapt-pkg.so.4.12.0[f758f000+13d000]
and the backtrace from gdb while dist-upgrading is:

Unfortunately there is no libapt-pkg-dbg package available, so the
backtrace is a bit non-informative.
