Hi there,
I'm stumbling over some memory leaks reported by MSVC when using boost::filesystem. Here is simple code sample that can reproduce the output below:
#define _CRTDBG_MAP_ALLOC
#include
#include #define BOOST_FILESYSTEM_VERSION 3 #include
namespace fs = boost::filesystem;
int main(int argc, char* argv[]) { fs::path my_path( "C:\\bla.dat" );
This object, my_path, has not yet gone out of scope. Why would you expect its memory to have been reclaimed in the line that follows? Cheers, Will
_CrtDumpMemoryLeaks();
return 0; }

I have a test suite that uses boost::filesystem in numerous areas and the output is somewhat disturbing to me.
