问题描述
似乎只要有静态对象，_CrtDumpMemoryLeaks 就会返回一个误报，声称它正在泄漏内存.我知道这是因为它们直到 main()(或 WinMain)函数之后才会被销毁.但是有没有办法避免这种情况?我用的是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，它允许所有静态对象都被考虑在内.我正在使用 log4cxx 和 boost 在静态块中进行大量分配，这修复了我的误报"...
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"...
在 main() 开头的某处添加以下行，而不是调用 _CrtDumpMemoryLeaks:
Add the following line, instead of invoking _CrtDumpMemoryLeaks, somewhere in the beginning of main():
_CrtSetDbgFlag ( _CRTDBG_ALLOC_MEM_DF | _CRTDBG_LEAK_CHECK_DF );
