Sadly, I can't reproduce this here…
And I think I figured out why. If I change the Version line and the
version in the Filename line, it only happens if the version is the same
as the version that I currently have installed, not if it's less or
greater. I'm going to assume you don't have dseomn-standard installed :)
Does it happen for you with (simulation mode, so no need for sudo):
apt-get --with-source ./Packages upgrade -s dseomn-standard
Yes, and also with apt-cache (ignore locale-en_US, it just does what it
says on the tin to make error messages in English):
$ locale-en_US apt-get --with-source /tmp/tmp.VtKyaCzPyr/Packages upgrade -s
NOTE: This is only a simulation!
apt-get needs root privileges for real execution.
Keep also in mind that locking is deactivated,
so don't depend on the relevance to the real current situation!

If so, add one by one:
-o Dir::state::status=/dev/null
-o Dir::Etc::main=/dev/null -o Dir::Etc::parts=/dev/null
-o Dir::etc::sourcelist=/dev/null
-o Dir::etc::sourceparts=/dev/null
Either of these two by themselves fix it:
-o Dir::state::status=/dev/null
-o dir::etc::sourceparts=/dev/null
I suspect its not crashing anymore if sources are disabled, so if you
could figure out which sources are needed to reproduce this would be
helpful. You can be either commenting out sources.list entries or adding
their Packages files from /var/lib/apt/lists to the apt call (before
your own Packages file). That isn't the same, the later might just be
easier to do but perhaps its doesn't trigger the problem. If we aren't
"lucky", its likely highly state dependent.
Even after adding all the Packages files from /var/lib/apt/lists, it
still didn't crash.
So I commented out all of my sources except for one, and it still crashed.
$ grep -rv '^#' /etc/apt/sources.list{,.d}
/etc/apt/sources.list.d/20-debian.sources:Types: deb
/etc/apt/sources.list.d/20-debian.sources:URIs:
https://deb.debian.org/debian
/etc/apt/sources.list.d/20-debian.sources:Suites: testing
/etc/apt/sources.list.d/20-debian.sources:Components: main
/etc/apt/sources.list.d/20-debian.sources:Signed-By:
/usr/share/keyrings/debian-archive-keyring.gpg
If I comment out that last remaining source, the crash goes away.
If so, a "silly" workaround might just be:
-o APT::Cache-Start=$((200 * 1024 * 1024))
(the default for that option is ~25 MB currently)
$ locale-en_US apt-get --with-source /tmp/tmp.VtKyaCzPyr/Packages -o
APT::Cache-Start=$((200*1024*1024)) upgrade -s

Description: dseomn-standard
I don't see something obviously wrong that should crash the parsers, but
that "description" is not what it should be in any sense of the word.
Yeah, I was just lazy because these packages shouldn't really be
published for anybody else. I just changed it to this though, and still
got the crash:
Description: foo
bar
.
baz
libapt7.0 did a bunch of std::string→std::string_view things and a crash
here might very well be a sign that either a string is not properly owned
any longer or you are lucky enough to hit a cache-growth problem that
are a pain to find and weed out.
In either case a backtrace for this crash would be useful. Please try
getting a coredump, preferably with -dbgsym packages installed.
(You might need to add a source for that… which might change the setup
and hence makes the problem disappear)
I've been using DEBUGINFOD_URLS=https://debuginfod.debian.net with gdb
lately instead of bothering with -dbgsym packages. Is there any reason
to install those packages instead of using the server?
See gdb.txt attached.
