boost:atomic<int>::is_lock_free() returns false on iPad 4 (armv7s) but returns true on iPad 3 (armv7).

Yes. I thought this had been fixed. It's now too long ago for me to recall exactly what happened. I know that I filed a trac ticket to get it fixed in smart_ptr's spinlock; I think that at that time Boost.Atomic has still not been reviewed and merged, and I probably fixed it only in a local copy.

btw, it may be worth to note that on iOS devices std::atomic should be available ...

Absolutely! Few people have any reason to be using Boost.Atomic. Regards, Phil.
