Sometimes when stopping/starting torrent [via rutorrent (xmlrpc)] rtorrent crashes.
Not sure if rutorrent is doing something bad or not, either way rtorrent shouldn't crash

Does rtorrent crash when you do start/stop using the ncurses interface? Also, do call this before doing backtrace;

Not sure if this is the same error tho?
When crashing it using rutorrent its with multiple torrents at once

That check is to detect bugs causing the client to hammer the trackers.
I'll need to fix that corner-case.

Try again but slower.

Not sure how to make it crash with the cli but via rutorrent is rather easy, stopping and starting multiple torrents results sooner or later in:

If it doesn't happen in the cli then I know where to look, though if it
actually does then I'd be wasting time in the wrong place.

Not sure how to make it crash with the cli but via rutorrent is rather
easy, stopping and starting multiple torrents results sooner or later in:

terminate called after throwing an instance of 'torrent::internal_error'

what(): Block dtor with 'm_state == STATE_COMPLETED && m_leader ==
NULL'

Program received signal SIGABRT, Aborted.

(15:00:22) Scheduled command failed: erasedata: ExecFile::execute(...) Fork failed.

in the log so I shut down rtorrent (ctrl+q) and got this:
