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.
Since you mentioned possible memory issues, here's the output of valgrind.

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!
