Creating and destroying SoundEffects causes crashes

[Michael Zanetti]

I keep on receiving bug reports about Machines vs. Machines being crashy on Ubuntu Phones and I tracked it down to the SoundEffect item. When playing without sound effects enabled, the game seems very stable.

To get to the bottom of this I created an app that simulates a bit how a game works with sound effects. It's a bit more aggressive than Machines-vs-Machines (still not really far fetched from a real game scenario) and reliably triggers some crashers in less than a minute here.

So far I've seen crashes in creating SoundEffects items as well as removing them from the scene.

Please find the example here: lp:~mzanetti/+junk/soundcrasher

You should be able to run it on any vivid powered device by just opening the .pro file in QtCreator and hit the play button. The logs vary a lot between crashes. Sometimes I get some PulseAudio messages, sometimes it just crashes without any. Probably some raciness. Anyhow, this example app should give the system a hard time and reveal most of the crashes eventually.

Status changed to 'Confirmed' because the bug affects multiple users.

you have to file upstream pulseaudio bug report if you can reproduce the crash and provide pulseaudio verbose log
