如何忽略来自_CrtDumpMemoryLeaks的假阳性内存泄漏？ [英] How to ignore false positive memory leaks from _CrtDumpMemoryLeaks?

问题描述

似乎每当有静态对象时，_CrtDumpMemoryLeaks返回一个假阳性声称它是泄漏的内存。我知道这是因为他们不会被销毁，直到main（）（或WinMain）函数。但是有什么办法避免这种情况吗？我使用VS2008。

It seems whenever there are static objects, _CrtDumpMemoryLeaks returns a false positive claiming it is leaking memory. I know this is because they do not get destroyed until after the main() (or WinMain) function. But is there any way of avoiding this? I use VS2008.

推荐答案

我发现如果你告诉它在程序终止后自动检查内存，对象被考虑​​。我使用log4cxx和boost在静态块中做了大量的分配，这固定了我的假阳性...

I found that if you tell it to check memory automatically after the program terminates, it allows all the static objects to be accounted for. I was using log4cxx and boost which do a lot of allocations in static blocks, this fixed my "false positives"...

添加以下行，而不是调用_CrtDumpMemoryLeaks ，在main（）的开头部分：

Add the following line, instead of invoking _CrtDumpMemoryLeaks, somewhere in the beginning of main():

_CrtSetDbgFlag ( _CRTDBG_ALLOC_MEM_DF | _CRTDBG_LEAK_CHECK_DF );
