release build error with ANE "AOT Compilation has failed while optimizing function"

I'm trying to use the ChartBoost ANE which can be downloaded here https://github.com/freshplanet/ANE-Chartboost

When I do an Ad-hoc release build It keeps crashing and giving me the error below when packaging for iOS. But if I do a debug build that's a "fast" or "standard" build it compiles fine, and I can even see the ads.

Why would it crash when doing a release build? Does this ANE need an update?

I'm using FB 4.7 and AIR 3.8. Specifically, Apache Flex 4.10 Air 3.8

If I remove this 1 line of the Chartboost ANE code "AirChartboost.getInstance().showInterstitial();", the release build compiles fine and I can put it on the test iOS device.

"Error occurred while packaging the application:
