[Christophe Dumez (hydr0g3n)]

This is a known bug in eglibc (used on recent Debian and Ubuntu) and libtorrent v0.15 because it uses vAlloc.
libtorrent v0.15 can easily be patched to use posix_memalign instead of vAlloc and avoid this issue.

Did you compile libtorrent v0.15 yourself?

[Christophe Dumez (hydr0g3n)]

Here is the patch I use for my Ubuntu packages (and the patch the Debian will probably use when he packages v0.15 for Debian).

If you really want to compile libtorrent yourself then you need to apply this patch and recompile from scratch (./configure && make clean && make).

Otherwise, you could probably use my PPA:
https://launchpad.net/~hydr0g3n/+archive/ppa

The patch is applied to my latest package and the crash should no longer happen.

[SDERAWI (sderawi-deactivatedaccount)]

Actually i just opened a terminal and it updated (miro miro-data libtorrent qbittorrent) after the update 2.2.2 started crashing.

P.S : I am already using your PPA

Thank for the quick response.

[Christophe Dumez (hydr0g3n)]

Ok. I have checked my PPA package and it seems the patch is not applied. I am uploading a fixed package to the PPA, you should get the update soon.

[SDERAWI (sderawi-deactivatedaccount)]

Thank you very much for your trouble Chris.

[Christophe Dumez (hydr0g3n)]

Package libtorrent-rasterbar - 0.15.0-0ubuntu4 is available and the patch was successfully applied this time.

Please reopen this bug report if you still experience the issue after the update.

[SDERAWI (sderawi-deactivatedaccount)]

Applied update but still not working

Indeed, it seems my patch is wrong after all. I'm trying a new one in -ubuntu5. Thanks for the feedback.

[SDERAWI (sderawi-deactivatedaccount)]

You are welcome and I hope it works.

Thanks again Chris.

[Christophe Dumez (hydr0g3n)]

Please confirm it works now :)

[SDERAWI (sderawi-deactivatedaccount)]

It works now using libtorrent-rasterbar 0.15.0-0ubuntu5 from your PPA.

Thank you.

[Christophe Dumez (hydr0g3n)]

Great news. Sorry for the confusion. It is not always easy to patch someone else's code.

[SDERAWI (sderawi-deactivatedaccount)]

Mariusz, we should talk with libtorrent author. As far as we know, the bug was only reproduceable with eglibc (instead of glibc). As far as I know, only Debian/Ubuntu use eglibc for now. Can you check exactly what libc your version of OpenSuse is using?

In the meantime, I suggest you apply my patch to your libtorrent package, it works fine.

[Mariusz Fik (fisiu)]

openSUSE 11.2 uses glibc-2.10.1 with many patches. I'll give a try to disable-valloc.dpatch then post feedback ;)

[SDERAWI (sderawi-deactivatedaccount)]

After the latest update , qbittorrent hangs and I have to force quit it.

this is the last thing reported to the terminal

A@A-Desktop:~$ qbittorrent
Peer ID: -qB2220-
HTTP user agent is qBittorrent v2.2.2
Warning: Local domain socket was not closed cleanly, deleting file...

(Where can I find the log for why qbittorrent hanged)

[Christophe Dumez (hydr0g3n)]

Does it hang on start up?
Does it hang all the time?

The last qBittorrent package update was merely a rebuild without any changes. It may not be related to the update.

[SDERAWI (sderawi-deactivatedaccount)]

It hangs in two to three hours of operation. the GUI freezes to the last stats when it hanged like for example 500 kb down 20 kb up.

P.S : I meant the last patch not the rebuild

[Mariusz Fik (fisiu)]

Chris, I applied a patch mentioned above for libtorrent-rasterbar 0.15.0. qbittorrent works fine so far...

Need some tests during Easter. Then we need to talk with Arvid.

[Mariusz Fik (fisiu)]

Not so good. qbittorrent run for few minutes then I got a crash:

Please subscribe to the other bug report.

[Christophe Dumez (hydr0g3n)]

Just so you know, I'm currently making changes on my PPA:
- Revert to libtorrent v0.14.10 (due to v0.15.0 instability)
- Update to qBittorrent v2.2.3 (fixes some minor bugs)

[SDERAWI (sderawi-deactivatedaccount)]

Well thank you , I really think it's better to have an old version that works rather than a new one with so many problems.

[Mariusz Fik (fisiu)]

I've just downgraded libtorrent too. I suppose to stick for openSUSE 11.3 with 0.14.10 - if it's stable...There will be a package version freeze in Factory for 11.3 soon.

[Christophe Dumez (hydr0g3n)]

Mariusz, v0.14.10 is very stable as far as I know. You should be safe.
