我刚刚在Windows 8上安装了Visual Leak Detector（2.3）。我使用空白的CRT程序（在Visual Studio 2012中）测试它，什么都不做。
#include <vld.h>
int main(int argc, char** argv)
{
return 0;
}
当我运行它时，VLD会在vc ++ crt模块中报告奇怪的泄漏：
Visual Leak Detector Version 2.3 installed.

网上没有太多关于此的详细信息，但在this msdn论坛中评论说：
那不是真正的泄密事故。为您的环境做好准备 执行＆＃39 ;.它正在制作流程环境的可写副本 对于期望它的程序，它们将在发布时发布 进程退出。您可以放心地忽略该报告。
但是，我想禁止这些行显示为报告（如果它们真的没有泄漏）
有没有人经历过这个并知道如何理清？

最简单的解决方案显然是在vld.ini文件中添加main()，然后从SELECT daytab7.pid, maxval_7day,maxvaldate_7day,maxval_30day,maxvaldate_30day
FROM
( /*picking top-most ranked value and corresp. date*/
SELECT PID, MY_VALUE MAXVAL_7DAY, VALUE_DATE MAXVALDATE_7DAY
FROM
( /*Assigning rank for range filtered values*/
SELECT PID, MY_VALUE, VALUE_DATE, RANK() OVER(PARTITION BY PID ORDER BY MY_VALUE DESC) RNK
FROM
( /*assigning row_number by ordering rows by value_date desc to get recent data for specified range of 7 days*/
SELECT PID, MY_VALUE, VALUE_DATE,
ROW_NUMBER() OVER(PARTITION BY PID ORDER BY VALUE_DATE DESC) ROW_NUM
FROM MY_TABLE
ORDER BY 1, 3 DESC
)
WHERE ROW_NUM <= 7
)
WHERE RNK = 1
) daytab7,
( /*picking top-most ranked value and corresp. date*/
SELECT PID, MY_VALUE MAXVAL_30DAY, VALUE_DATE MAXVALDATE_30DAY
FROM
( /*Assigning rank for range filtered values*/
SELECT PID, MY_VALUE, VALUE_DATE, RANK() OVER(PARTITION BY PID ORDER BY MY_VALUE DESC) RNK
FROM
( /*assigning row_number by ordering rows by value_date desc to get recent data for specified range of 30 days*/
SELECT PID, MY_VALUE, VALUE_DATE, ROW_NUMBER() OVER(PARTITION BY PID ORDER BY VALUE_DATE DESC) ROW_NUM
FROM MY_TABLE
ORDER BY 1, 3 DESC
)
WHERE ROW_NUM <= 30
)
WHERE RNK = 1
) daytab30
WHERE daytab7.pid = daytab30.pid
的第一行显式启用它。当然，你也会错过＆＃34;内存泄漏＆＃34;来自你的全球物品，但这通常同样无害。

我发现这是VLD 2.3中的错误。错误的详细信息是here。我刚刚下载了v2.4rc2（vld-2.4rc2-setup.exe），这个问题似乎不再出现了。 （我已经下载了v2.3，因为它已被标记为稳定）
