Segmentation fault on start

[Martin Milata]

After starting mixxx for the first time, it starts drawing the interface to the screen then crashes.

Version: mixxx-1.11.0-2.fc20.i686
Environment: Fedora 20, i686, no jackd

[Daniel Schürmann (daschuer)]

Thank you for the bug report.

It looks like an intel bug:
https://www.libreoffice.org/bugzilla/show_bug.cgi?id=69823
https://bugzilla.redhat.com/show_bug.cgi?id=1053407
http://lists.freedesktop.org/archives/intel-3d-bugs/2014-January/000339.html

Please open

/home/<user>/.mixxx/mixxx.cfg

and set

[Waveform]
WaveformType 0

Restart Mixxx.
Now you can go to preferences->Interface and check for working waveform types.

Can you please check if the current master Mixxx 1.12 alpha is effected as well?

Please follow:

Thank you very much!

[Daniel Schürmann (daschuer)]

This is an argument for Bug #1017858

[Martin Milata (b42-3)]

Setting WaveformType to 0 does not help. Current git master is affected too.

Does not happen on 64-bit computer with Fedora 20 and different intel GPU, unsurprisingly.

[Owen Williams (ywwg)]

Can you generate another backtrace with waveformtype set to zero? Please use the directions here: http://mixxx.org/wiki/doku.php/creating_backtraces

[Martin Milata (b42-3)]

Here's a backtrace from 4054cf2e9a89df36a280f53ce122e4cd595fe4b2 with WaveformType = 0. Let me know if you need anything else.

[Martin Milata (b42-3)]

Btw, the git version does not crash with --safeMode.

Anyway, if this bug is specific to my now-ancient gpu then I guess you should not waste too much time on it:) I can play with mixxx on my other laptop which is not as old.

I have same problem with mixxx. It crashes on startup.

This effects an old Version of Mixxx, so I will close it now.
Please file a new bug if this happens again with a recent version of Mixxx.
