4.3.3 Download AssetBundle crashes on iOS

Unity Engine
1

I have attached a very simple project where an assetbundle (a cylinder primitive) gets downloaded.
It works in editor but crashes on iPad (iOS7).

Can anyone confirm a bug?

Having the same issue even with the hotfix in 4.3.4. What I can say for sure, the game crashes on iPad mini with iOS 7.0.3, also on iPod 4 iOS 6.1.5, but it does work fine on iPad 3 with iOS 6.0.1. Moreover, before the hotfix on 4.3.3, the game wasn’t actually crashing, it was throwing an exception with something about iterator.MoveNext() method, and we could catch it within the game (custom debug console). But, since we updated to 4.3.4 it started crashing completely.

P.S. I’ve noticed that almost all the time the game crashes while loading the second bundle(not the first one) in a row. And there was a case where it crashed while loading the 7th or 8th bundle in a row. About the way we load this bundles, in the first game launch we are caching all the bundles from a listing by loading them one by one and after finishing the load of each one, we just unload it in order to keep memory clean, and further, when they are needed we load them.

P.P.S. Everything works fine on Android devices.

Are you loading than second bundle from file:// or http:// URL ?

The second one: http:// URL

Oh, another thing I must have mentioned that those bundles are actually scene bundles, not assets.
