I'm not sure if that is reliable. It's possible that the optimizer sees that the lifetime of the objc_precise_lifetime variable is strictly contained within the lifetime of `self`. The compiler "knows" `self` is alive, so it might decide it can omit any retains and releases from the objc_precise_lifetime variable. -- Greg Parker gpar...@apple.com Runtime Wrangler _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
