I\'m writing a graphically intense game for the Nexus One, using the NDK (revision 4) and OpenGL ES 2.0. We\'re really pushing the hardware here, and for the most part it works
I don't believe such error can occur in audio code, SharedBufferStack is only used in Surface libraries. Most probably this is a bug in EGL swapBuffers or SurfaceFlinger implementation, and you should file it to the bug tracker.
