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 <stdlib.h> #include <crtdbg.h> #define BOOST_FILESYSTEM_VERSION 3 #include <boost/filesystem/convenience.hpp> namespace fs = boost::filesystem; int main(int argc, char* argv[]) { fs::path my_path( "C:\\bla.dat" ); _CrtDumpMemoryLeaks(); return 0; } -- Output: 'test.exe': Loaded 'C:\gil_contributions\solutions\vc10\test\x64\Debug\test.exe', Symbols loaded. 'test.exe': Loaded 'C:\Windows\System32\ntdll.dll', Cannot find or open the PDB file 'test.exe': Loaded 'C:\Windows\System32\kernel32.dll', Cannot find or open the PDB file 'test.exe': Loaded 'C:\Windows\System32\KernelBase.dll', Cannot find or open the PDB file 'test.exe': Loaded 'C:\Windows\System32\msvcr100d.dll', Symbols loaded.

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