Crashes in ObjC runtime and/or autorelease operations are almost always a dangling pointer.

I highly doubt this is related to the environment. More like, there's just a code path/edge case that you aren't seeing during normal development. I'd start with NSZombies, which can be really helpful.

I'd also recommend looking through your Crashlytics crashes for strange unrecognized selector crashes, or other things in runtime code. They could all potentially be related to the same underlying root cause.
