Package: apt
Version: 0.9.7.9+deb7u6
Severity: important
File: /usr/bin/apt-get

If I try to install libpango-1.0 from testing on a stable system apt-get crashes:

# apt-get install libpango-1.0-0/testing
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Segmentation fault (core dumped)

If I try:

apt-get -t testing install libpango-1.0-0

It doesn't crash but does try for an enormous amount of changes.

It also doesn't crash on other packages.

Here is a backtrace with debugging symbols:

Hi, thanks for your bug report. I am closing it, as it seems like
your cache file was broken somehow.

Reason: P.InstVerIter contains an iterator for the InstallVer pointer,
and ->InstalledSize is the same as InstallVer->InstalledSize, and
we check that InstalledSize != NULL.

If you can still reproduce it, please re-open.
