Asset bundle decompression is crashing Unity 5.3.1p3

Hi,
I'm having wierd problem with asset bundles. When I run game on iOS device, I get crash when the game is trying to load asset bundles from the cache, it gets stuck on DecompressAndStore().
I have tried to use this function on Awake() - Caching.compressionEnabled = false, but still the error is the same.
The game is working fine when it loads the asset bundles for the first time, but later it always crashes in some random places when I have unload them and try to load again.
The same code...
