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: Reading changelogs...
