Description Michael Schwendt 2010-12-06 18:04:08 EST
abrt version: 1.1.14
architecture: i686
Attached file: backtrace
cmdline: audacious2
component: audacious
crash_function: xmp_smix_softmixer
executable: /usr/bin/audacious2
package: audacious-2.4.0-3.fc14.1
rating: 4
reason: Process /usr/bin/audacious2 was killed by signal 11 (SIGSEGV)
release: Fedora release 14 (Laughlin)
time: 1291674709
uid: 500

How to reproduce
An ancient MOD file crashes the XMP plugin for Audacious whereas "xmp" cli rejects the file.

Note that the file is valid, but since it is very complicated to safely detect the specific MOD format it uses, most multi-format MOD players either fail at playing it correctly when using automated format detection.

On F-13, this update works for me: https://admin.fedoraproject.org/updates/xmp-3.3.0-1.fc13 ? Could you try the corresponding F-14 update https://admin.fedoraproject.org/updates/xmp-3.3.0-1.fc14?

What modfile format is it? I'm sure upstream will be interested anyway (I'm sending the sample), but any additional information will be welcome.
Comment 4 Dominik 'Rathann' Mierzejewski 2010-12-06 19:01:05 EST
And by "works for me" I meant it doesn't crash.
Comment 5 Michael Schwendt 2010-12-07 01:35:27 EST
Oh, thought ABRT would have handled that. :) This is specifically about

  $ rpm -q audacious-plugin-xmp audacious

and downgrading the xmp plugin doesn't help. So, it's not regression caused by the test update. F13 is an older Audacious. Will need to try.


The file format is Soundtracker older than 2.3, but not Ultimate Soundtracker compatible. Detecting it 100% is non-trivial, but that's not the reason for this ticket. A player/plugin should not crash and trigger ABRT as such mod files are still out in the wild.

Comment 6 Michael Schwendt 2010-12-07 02:29:39 EST
New test-case for F14:

1. start Audacious
2. disable ModPlug plugin
3. clear playlist
4. add file Angie_S.mod to playlist
4.2. file isn't detected (length 0:00) but added
5. add any other accepted MOD file to playlist
6. start playback with Angie_S.mod

What happens is that the file _is rejected_ just as with "xmp" cli, but when the playlist position jumps to the next track, the XMP plugin crashes.
