I had the same error with web_seed_entry:

The problem was that I compiled static libtorrent-rasterbar WITHOUT geoip support (TORRENT_DISABLE_GEO_IP is set by default by cmake generator)
but qbittorrent was compiled WITH geoip support.
So web_seed_entry had different sizes (208 bytes vs 200 bytes), and it' fields had different offsets.
That's why default copy constructor of web_seed_entry crashed program.
Compiling both qb and libtorrent with the same geoip options fixed this issue.
