IOS Air Application crashes without info

our team has been struggling for 2 weeks (Working and Personal), with the following issue regarding Ios deployment and Adobe Air. Below is a detailed message entailing the Application, our issue. If anyone can help us in debugging this task we'd greatly appreciate it.

The team is using IntelliJ/Flashbuilder setup with airsdk 17, the below description also affects AirSdk19, and the Beta Build AirSDK20. We are attempting to compile an Adobe Air project on IOS but are meeting a lot of trouble when an app is compiles using the AOT compiler mandated by Apple (our android app runs just fine using the JIT compiler).

Before I get into our issue, I'd like to discuss the App we are developing how it works, along with any specifications that may or may not be helpful in the Help Session.

How the App works: The way we have our App setup is we have a series of Activities each in their own swf, and the main app which is in it's own Swf aswell. Activities fall into two types: Explanation Activities and Challange Activities. All challange activities inherit from an ItemActivity Class, meanwhile all Explanation Activities inherit from an ItemActivityVideo class which in turn inherits from ItemActivity.

Our Inheritance structure for Activities is as Follows:

Explanation Activities:

Main (Specific for Each Activity) <- ItemActivityVideo <- ItemActivity

Challange Activities:

Main (Specific for Each Activity) <- ItemActivity.

The main Swf has a series of screens one of which the "ItemSelect" screen lays out a web of buttons each directing the app to load up one of the external activity swfs. All swf's are hosted locally alongside the main swf so there are no network calls when it comes to item Loading.

The Explanation Activities are the only ones that utilize sound this is located inside a "Voice Controller" class, whenever this class is referenced (simply via an instruction such as "new VoiceController()), the Ios App crashes, also certain item's are crashing at various parts of the timeline without any indication as to why from the Flash Debugger nor the crash log. The Debugger simply prints "Player Session Exited", meanwhile the crashlog results in a segfault signal "SigSegV", without any indication as to what caused the memory misuse.

Any assistance in helping our team be able to debug this Issue would help us out greatly, we are also having issues in regards to symbolicating the crash log using the dsymutils due to the drastic changes between the current Apple architecture and Adobes' dated documents.

Below is a segment of the Crash log of our App:

Anything can crash your Ios app while not crashing the Android version, for example: file names. You could load a sound called "test.mp3" and really called in file system "Test.mp3" and it will work in debugging, work in Android, even play a few times in Ios and then crash the app. All filenames in Ios should be lowercases and not contain fancy characters. In general debugging Ios app in AIR is really coming down to tracing only, there's no real easy way to translate a DYSM to anything meaningful in AS3 so trace, trace, trace. I work in each project with an extended Sprite class that can remove all its registered listeners in one call. Very handy but the first version was crashing in Ios pretty randomly. I put traces all over and finally figured that my last trace was just before a 'removeListeners()' call. So I commented out the method code and no more crashes. Then I reworked the system to make it more solid and everything finally worked fine without any crashes in Ios.

So to summarize:

• In Ios if loading anything externally pay close attention to file names, they should be lowercases and not contain fancy characters or else ... watch for crashes!

• To debug and really know what's going on there's only trace, put trace everywhere and watch for the last one, the faulty code will be right after. I do have a system that outputs all trace real time to a server so I catch them even in testflight installs. Put something similar together.
