Comment (by marcus.alanen@…):

 Hello,

 we've also had crashing bugs on a multithreaded game with shared_ptrs on
 iPad2 - very mysterious of course, and not easily testable.

 I tried adding dmb instructions as per suggestion 1 above by pdimov, and
 after some casual testing so far we haven't had any issues. However, this
 is of course no guarantee, but I hope this at least gives you something.

 Best Regards,[[BR]]
