Description Ilja Sekler 2012-09-20 13:05:44 UTC

Description of problem:

The 'playmus' tool from SDL_mixer crashes or hangs indefinitely on exit when playing Extreme Tux Racer music files (/usr/share/etracer/*.it):


playmus /usr/share/etracer/music/start1-jt.it 
Opened audio at 22050 Hz 16 bit stereo (LE), 4096 bytes audio buffer
Playing /usr/share/etracer/music/start1-jt.it
^C*** glibc detected *** playmus: free(): invalid pointer: 0x0000000000fa33f0 ***
======= Backtrace: =========
/lib64/libc.so.6(+0x7bfee)[0x7f7f01727fee]

/lib64/libc.so.6(__libc_start_main+0xf5)[0x7f7f016cd735]
playmus[0x40145d]


playmus doesn't crash, when the linked in or preloaded libmikmod.so.3.0.0 has been built without Fedora patches, but many voices are missing then, similar to Ubuntu bug <https://bugs.launchpad.net/etracer/+bug/194916> for libmikmod 3.1.11. Unfortunately, SDL_mixer in F17 doesn't like libmikmod.so.2, so no simple workaround.


Version-Release number of selected component (if applicable):

rpm -q libmikmod
libmikmod-3.2.0-18.fc17.x86_64

rpm -q SDL_mixer
SDL_mixer-1.2.12-3.fc17.x86_64


How reproducible: Always.


Steps to Reproduce:
1. Install extremetuxracer, which pulls in SDL_mixer and libmikmod.
2. Run 'playmus /usr/share/etracer/music/start1-jt.it'
3. Hit 'Ctrl+C' or wait till EOF is reached.
  
Actual results: Crash


Expected results: playmus quits cleanly.


Additional info:

I assume that this is the cause of Extreme Tux Racer being broken on Fedora 17, always hanging or crashing when starting a race, which tries and fails to stop the playback of "start1-jt.it" before loading "race1-jt.it".

Comment 1 Hans de Goede 2012-09-26 18:07:52 UTC

Thanks for the report, this is caused by libmikmod-CVE-2007-6720.patch being a bit overzealous in checking some things. A fixed package is on its way!

Comment 6 Ilja Sekler 2012-09-28 21:52:19 UTC

I am happy to confirm that libmikmod-3.2.0-19 fixes this bug as well as various sound distortions when playing Extreme Tux Racer music files, not mentioned in this bug report. The game runs impeccably now.

Tested on Fedora 17 x86_64 and on Fedora 18 i686 (well, briefly tested before an unrelated update for F18 completely broke TTYs).

Thanks a lot!

Great, if you can login and then add some positive karma here:

That will expedite other users getting the fixed version.

Thanks,
