How to ignore false positive memory leaks from _CrtDumpMemoryLeaks?

Question

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 unti

Answer 1

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"...

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

_CrtSetDbgFlag ( _CRTDBG_ALLOC_MEM_DF | _CRTDBG_LEAK_CHECK_DF );
