3 years ago This smells like an ABI incompatibility. Did you build libtorrent yourself, but you use someone else's build for qBittorrent? If so, are you sure they are built with compatible options? Do you have the build log for qbittorrent too?

3 years ago I used the builds of libtorrent and qBittorrent both in this PPA: https://launchpad.net/~poplite/+archive/ubuntu/qbittorrent-enhanced/ Build of qBittorrent: https://launchpad.net/~poplite/+archive/ubuntu/qbittorrent-enhanced/+build/20908342 Build log of qBittorrent: https://launchpadlibrarian.net/518393015/buildlog_ubuntu-focal-arm64.qbittorrent-enhanced_4.3.3.10-1ppa1~focal1_BUILDING.txt.gz

3 years ago I tried to debug using gdb with debug symbols of libtorrent and qBittorrent from this PPA: https://launchpad.net/~poplite/+archive/ubuntu/qbittorrent-enhanced/ and found a different way to crash.

3 years ago It seemed that all of these three errors are related to libtorrent::announce_entry.

Which is one of the reasons I think this smells like an ABI issue.

please describe what symptom you see, what you would expect to see instead and how to reproduce it. qbittorrent-enhanced-nox crashed a few times radomly. It seemed that the crashes are caused by libtorrent. I have seen two different kinds of errors so far.
P.S.
