Iphone SDK Utility Application template has leak

That might be a leak or it might not be a leak. If you were to add the backtrace of the allocation, that would be helpful.

More likely than not, it isn't a leak, but some bookkeeping information that is being stashed away by dyld that leaks/Instruments loses track of.

Given that it is 128 bytes and I'm guessing there is only one of them, I would encourage you to file a bug via http://bugreport.apple.com and then forget about it for now as, in the unlikely case that it really is a leak, you will be equally as unlikely to be able to fix it from within your application.

Hope this helps.

"The simulator has bugs related to singletons and llvm stuff that are incorrectly reported by Instruments. Always check your leaks on the device itself."

Got the leak doing this:

XCode 3.2--

File, New Project, Navigation-based Application
Give it a name
Build It
Run With Performance Tools -> Leaks

When Instruments comes up, click on Leaks (you might have to click the little icon at the bottom that looks like four boxes within a box)

About 7 seconds after running you should see the leak:-- Malloc 128 Bytes, some Address, 128 Bytes, CoreGraphics, open_handle_to_dylib_path

I traced it to this code in the AppDelegate:

//APPLE CODE- (void)applicationDidFinishLaunching:(UIApplication *)application {        // Override point for customization after app launch        [window addSubview:[navigationController view]];    [window makeKeyAndVisible];}

I broke out the navigationController (did a separate alloc and release) and COMMENTED OUT the addSubview: action - there was no leak - and, obviously, the screen was blank.

It wasn't until I attempted addSubview that the leak occurred. Since there are numerous ways to add a subview, I tried those. Each resulted in the leak or a blank screen.
