当我运行以下代码时：

#include "gmock/gmock.h"
#include "gtest/gtest.h"

#define _CRTDBG_MAP_ALLOC
#include <crtdbg.h>

int main(int argc, char **argv) 
{
    ::testing::InitGoogleTest(&argc, argv);
    _CrtDumpMemoryLeaks();
    return 0;
}

我得到以下输出：

我究竟做错了什么？

解决方法:

你没有做错任何事. “内存泄漏”来自静态初始化的google测试单例类的堆分配.

以下是谷歌测试FAQ：How do I suppress the memory leak messages on Windows?的答案
