Can you reproduce the problem?
(In reply to comment #1) > Can you reproduce the problem? Everytime on all my gentoo boxes. - marcel@yoriko ~ % rtorrent - Then press backspace and add a torrent file (for example http://torrents.gentoo.org/torrents/install-x86-minimal-2006.1.torrent) - Press [ctrl]+d to stop the torrent and again [ctrl]+d to remove the torrent file (or just wait until the download is complete...) - Crash: rtorrent: ChunkList::clear() called but a valid node was found.
It happened to me one time, but now it's working fine. Can you please report this upstream?
(In reply to comment #3) > It happened to me one time, but now it's working fine. Can you please report > this upstream? As long as there is a 0.0 / x download it works fine, but when some KBs are downloaded rtorrent crashes as already explained. I tried to create a backtrace but gdb just tells me --- (gdb) exec-file /usr/bin/rtorrent (gdb) run Starting program: /usr/bin/rtorrent /usr/bin/rtorrent Using host libthread_db library "/lib/libthread_db.so.1". (no debugging symbols found) [...] (no debugging symbols found) rtorrent: ChunkList::clear() called but a valid node was found. Program exited with code 0377. --- I emerged rtorrent and librtorrent with the debug USE-Flag.
The debug useflag enables extra debug code, not debugging symbols. Please use http://www.gentoo.org/proj/en/qa/backtraces.xml to get a meaningful backtrace (upstream will ask for it, too).
Now I just get this: Starting program: /usr/bin/rtorrent rtorrent: ChunkList::clear() called but a valid node was found. Program exited with code 0377.
I get the same sort of Errors: Hashing: Storage error: [Hash checker was unable to map chunk: Cannot allocate memory] This is working with an Older torrent I was trying to download, on closing, I get: rtorrent: ChunkList::clear() called but a valid node was found.

According to a post on the rtorrent mailing list, this problem occurs with GCC 4.1.1 using -O2: http://rakshasa.no/pipermail/libtorrent-devel/2006-October/000887.html The problem does not occur for me when I change the -O2 in my CFLAGS ("-O2 -march=athlon-xp -mtune=athlon-xp -fomit-frame-pointer -pipe") to -O3.
Changing the CFLAGS from " -O2" to "-O3" solves the problem. Updated ebuilds are in portage now, so bug is fixed. ;)
