ios – 仪器在main.m(Xcode 4.3.1)中显示泄漏

我正在开发一个使用ARC的应用程序
当我的应用程序在仪器中分析内存泄漏时,会显示以下功能的泄漏：

#import <UIKit/UIKit.h>

#import "AppDelegate.h"

int main(int argc,char *argv[])

{
    @autoreleasepool { 
       return UIApplicationMain(argc,argv,nil,NsstringFromClass([AppDelegate class]));
    }
}

这是否表示我的代码中的其他地方有问题？

这是堆栈跟踪

解决方法

它似乎是iOS 5.1框架中的一个错误：
