Description Walter van Niftrik 2017-02-12 00:29:09 UTC 
We have found that since SDL 2.0.5 the audio callback thread is created with a very small stack size. In our application this is leading to stack overflows.

We believe there is a bug at http://hg.libsdl.org/SDL/file/5a77f977ad95/src/audio/SDL_audio.c#l1132, where the is_internal_thread flag appears to be inverted.
