After a few hour searching for a memory leak, the cause seems to be related to the following line: boost::filesystem::path full_path( boost::filesystem2::current_path() ); or boost::filesystem2::current_path(); I'm loading the boost filesystem library as a dynamically linked library ( boost_filesystem-vc100-mt-gd-1_44.dll ) in a MFC application using VC++ 2010. I'm calling the current_path function during the application's InitInstance method. I'm a little clueless about the cause of the memory leak, so any suggestions would be helpful. I doubt the the memory dump will be useful, but here it is: Detected memory leaks! Dumping objects -> {285} normal block at 0x00036578, 80 bytes long.
