I'm getting this crash with 124 (and I don't think it ever happened with 123, but I may just have been passing in different parameters).  Anybody know whats going on?

My device logs are full of this too. I was able to pinpoint the bug to getting and setting booleans through interfaces.

Here's a sample app which fails on every run:

https://www.dropbox.com/s/1onrm3kdwaxczwq/src.zip?dl=0

Notes:

- App fails only in debug mode

- App works fine with fast packaging

- Variable test has to be of type ITest. Using type Test works fine.

- First getBool() returns correct value (true)

- false is passed to setBool(), but if you put a break point into setBool() you'll see that it gets a true as parameter.

- Second getBool() either crashes the app, or gets traced as "(null)"

Setup:

I have also encountered this issue with booleans in a project. I am currently trying to find which AIR revision it occurred in.

I didn't try that minimal repro test, but the circumstances are identical to what I have encountered in my code. I was able to get something that corrected the issues in the places I was using it in, with something similar to :

var value:Boolean = !Boolean(test.getBool());

It seems that the coercion is not working correctly when accessing a boolean value via an interface and it requires an explicit cast. This is using the flex compiler, just in case that is different here to the ASC 2.0 compiler.

This is quite a nasty bug.

joulupuqqi‌ could you please log a bug in the bugbase, with your minimal repro code : Adobe Bugbase

if you do I will vote it up immediately!

Crashes just fine in adhoc IPA builds. Worked around the issue by converting a specific property to integer

I actually seem to have a different problem from the coercion problem.  I have traced the code to this statement:

var questions:Vector.<MCQuestion> = new Vector.<MCQuestion>;

The execution does get to the global$init code in MCQuestion class, presumably to get the size of the instance.   The interesting thing is that the MCQuestion class has this declaration:

private var _choices:Vector.<MCChoice>

It crashes before getting to the global$init code in the MCChoice  class.  So I think my problem is setting up a Vector containing a class that itself contains a Vector.
