Errors with Alien Bob's libtorrent-rasterbar and qbittorrent packages.
 

I have been running Alien Bob's slackware packages (not from source, his builds) of libtorrent-rasterbar and qbittorrent and it has worked perfectly fine. Now on -current I compiled them from source using his builds and I get a silent crash anywhere between 10 sec to 5 minutes. Output...

I went back to 13.1 and removed the packages and built them from source and it started happening in 13.1 too. Some how when I build them on my machine this happens. But I don't see any errors and both of the builds finish without problems... so right now I am stumped.
Any Ideas appreciated. Thanks.

Probably it's due to changes in the toolchain.
qBittorrent has newer version. Try to use the SlackBuild to compile the new one
http://qbittorrent.sourceforge.net/download.php

I just tried the newest version 2.6.6 and it still crashes with the same error. This is definitely weird since Eric's binary packages worked fine.

qbittorrent 2.6.6 seems to work fine here, on 64-current multilib, with libtorrent-rasterbar-0.15.5 (I just added them to SBo-git ;) ).

well, it seems that you probably missed an update on your system then :)

I just updated slackbuilds.org version (in pending) to 2.6.6. Runs ok on 32bit, will test x86_64 a bit later when I can get on the server.

Just built the new package from Alien Bob and all is well now. Marked as solved.
