Incorrect. @autoreleasepool does everything that NSAutoreleasePool does on
exceptions. (In fact, @autoreleasepool fixes a small leak that
NSAutoreleasePool suffers.)
You may be thinking of ARC. ARC is expected to leak on exceptions unless you
pass a special compiler flag. @autoreleasepool does not require ARC.
