According to the Clang documentation, objc_loadWeak retains and autoreleases the object and is equivalent to id objc_loadWeak(id *object) { return objc_autorelease(objc_loadWeakRetained(object)); } This (hopefully) explains why both if(strongPtr == weakPtr) … and NSLog(@”weakPtr: %@”, weakPtr); create additional autoreleased references.
