I’m getting the following crash when using AVAudioSession with AVAudioEngine. What I don’t understand is why InterruptionListener is listed twice in the stack trace. Does this mean it’s somehow being called again before it has returned? Is this likely to be a concurrency issue?

There is some info about crash on AFNetworking github page (https://github.com/AFNetworking/AFNetworking/issues/3003), but they closed it and pointed to fabric(https://twittercommunity.com/t/crashes-on-ios-7-after-updating-to-3-3-4/54693/15).
But disabling nor AFNetworking nor Fabric not helped me.
I tried to migrate to NSURLSession, but it did not help.
I've figured out that application crashing more if there is more POST requests. Disabling POST requests seems to eliminate crash completely.
I do not know where to dig further. Maybe someone has come across this. I will be glad to any help!
I have a UIWebView based iOS application which has recently started crashing quite a lot. I strongly believe the crash is caused by something that has changed in the web content (worst-case, but maybe most likely, scenario is it's a 3rd party banner ad), since the crash reports started to come in for all version of my iOS app on the same day, suddenly going from 0 to several hundred crashes.
Here is the crash stack trace on iOS9:

On iOS8 it crashes with a slightly different but very very similar stack trace. The iOS8 and iOS9 crashes started at the same time so it's undoubtedly the same thing.
Given the OpenGLES references in the crash report I suspect it has something to do with DOM rendering involving the hardware. Has anyone else developed a hybrid web app and seen these crashes? Any specific CSS transforms/transitions that caused the app to crash this way?
Also, there's a reference to WebGLRenderingContextBase, does that mean that it must be caused by actual WebGL on the web page or could it still originate just form non-3D CSS styles?
I get Xcode quit unexpectedly while using the SimplePlayer plug-in.
simpleplayer is the name of the app.
Xcode 6.2 only happens in simulator. IOS target 8.1 and above. App works normal without breakpoint.
This only happens when I set the breakpoint in the completion callback.

my app crash in IMGSGX543GLDriver ,the most difficult is there are not any code of my app in the crash log and i cannot reproduce it .This issue cost me several days and I still have no idea. Any ideas you guys provide, I will try. Thank you for your help.
