Package: libapt-pkg4.12
Version: 0.9.3
Severity: serious
Justification: renders package unusable

Hi,

when running 'apt-get dist-upgrade', the command segfaults on amd64
after pressing 'y' in order to continue after the changes summary. The
segfault happens in pkgPackageManager::SmartUnPack() (according to gdb).
Looking at the backtrace, I suspect an endless loop filling up the stack
space.

This does *not* happen when running 'apt-get install <pkg>' (with extra
packages being installed).

See below for details:

Closes: 673294 673815
Changes: 
 apt (0.9.5) unstable; urgency=low
 .
   [ Chris Leick ]
   * proofreading of the manpage pot
   * German manpage translation update (Closes: #673294)
 .
   [ David Kalnischkies ]
   * buildlib/podomain.mak:
     - ensure that all sources end up in the srclist so that we don't
       forget to extract half of the translation strings
   * buildlib/inttypes.h.in:
     - remove inttypes.h compatibility as providing such a c99 types
       compatibility conflicts with the usage of c99 type long long
   * apt-pkg/contrib/mmap.cc:
     - have a dummy SyncToFd around in case of ReadOnly access to a
       compressed file as we otherwise on Close() do not delete[] the
       char buffer but munmap() it… (Closes: #673815)
   * debian/control:
     - moving debiandoc-sgml to Build-Depends-Indep was one step too much
       for the buildds as we still build two sgml files in arch:any
   * debian/rules:
     - move internal-solver as 'apt' to his friend dump-solver in
       /usr/lib/apt/solvers to avoid writing a manpage for it
