[Normally I’d ask for a full crash report, per the instructions in Posting a Crash Report, but TeeMo_Y sent me one via other means.]
Looking at the crash report this is clearly a memory corruption issue. The question is whether this is caused by your code or by something inside iOS. Based on some internal analysis I suspect that it’s the latter. If so, there’s probably not much you can do about it.
How easily can your reproduce this problem?
