After upgrade boost-libs from 1.72.0_7 to 1.79.0_1 and rebuild net-p2p/libtorrent-rasterbar and net-p2p/qbittorrent I'm getting:

$ qbittorrent
Bus error (core dumped)

There were no function names found in the stack trace
.Seems like debug symbols are not installed, and the stack trace is useless.
Consider installing debug symbols for packages containing files with empty function names (i.e. empty braces "()") to make your stack trace more useful

Comment 3 Yuri Victorovich freebsd_committer freebsd_triage 2022-05-27 17:12:36 UTC 
I also notified the libtorrent upstream author/maintainer via e-mail.

That's the most I can do.
Comment 4 Daniel Engberg freebsd_committer freebsd_triage 2022-05-27 22:38:37 UTC 
Bumping libtorrent to the latest commit for 2.x-branch and qbittorrent 4.4.3.1 worked fine for downloading a few torrents on 13.1-STABLE (amd64)
Comment 5 Daniel Engberg freebsd_committer freebsd_triage 2022-05-27 22:39:18 UTC 
...and force using c++17 for both ports
Comment 6 Yuri Victorovich freebsd_committer freebsd_triage 2022-05-27 22:50:57 UTC 
(In reply to Daniel Engberg from comment #5)

Ok, I'll try it tomorrow.


Thanks!

Daniel.

I tried revision v2.0.6-27-g34c75eb5f of libtorrent-rasterbar but after rebuild of it and qbittorrent qBT still crashes.

Comment 8 Yuri Victorovich freebsd_committer freebsd_triage 2022-05-28 02:28:15 UTC 
(In reply to Yuri Victorovich from comment #7)

But with the c++17 flag it works now.

I'll update the ports soon.


Thanks!
