aptitude segfaults during dependency resolution

Bug description:
[Impact]
Aptitude regularly crashes when trying to mark packages for deletion
due to an infinite loop in a recursive function (improperly handled
circular dependencies).
[Test Case]
On a fresh English install of Ubuntu 15.10 desktop:
1. Start up aptitude: sudo aptitude
2. Mark the following packages as automatically installed (select them and
press Shift-M):
* language-pack-en
* language-pack-en-base
* language-pack-gnome-en
* language-pack-gnome-en-base
Aptitude should now show all four packages as marked for deletion.
3. Mark language-pack-gnome-en-base for purge by selecting it and pressing
'_' (underscore).
If the bug is not fixed, aptitude will crash. (Your terminal will
likely be in a bad state. Run 'reset' to fix it.)
[Regression Potential]
The patch alters the logic used to automatically mark packages for
deletion. Any regressions should appear there.
The patch is cherry-picked from the upstream Git repository, so
upstream recognizes the bug and approves of this fix. However,
upstream might have committed additional related changes (e.g., to fix
a hypothetical flaw in this patch) without us realizing it.
[Original Description]
Hi.
I just installed a new Ubuntu MATE 15.10 for my mom and I was
selecting packages when aptitude simply crashed. I am using (for
reasons beyond my control right now) the 32 bit version if that
matters.
I don't know if I can reproduce the problem or not, but I may try
(despite the fact I do not have frequent access to this computer).
If any further information is needed, please let me know.
Thanks,
Rogério Brito.
