Android 6.0 Nexus 6 Crash in Adreno 420 driver

Question

I use the general OpenGL context for several GLSurfaceView . After switching from one activity to another, the adreno driver crashes. But my application works well on other devices. Also, it works if I replace the general context with a regular context. Is this a bug in the driver?

Here's the crash log:
