This problem still exists in 1.64. Make a link in Windows, and pass a path that includes the link to testBoost in the following:

std::atomic<int> boostResult(0);
void boostThread(const std::string& _path)
{
  try {
    boost::filesystem::path boostPath(_path);
    boost::filesystem::path canonicalFile = boost::filesystem::canonical(boostPath);
    std::string canonicalPath = canonicalFile.string();
    //std::cout << "canonicalPath: " << canonicalPath << std::endl;
  } catch (boost::filesystem::filesystem_error &e) {
    std::cerr << e.what() << ", failed to resolve path" << std::endl;
    ++boostResult;
  } catch (std::exception &e) {
    std::cerr << e.what() << ", failed to resolve path" << std::endl;
    ++boostResult;
  }
}
int testBoost(const std::string& _path)
{
  std::cout << "Testing path: " << _path << std::endl;
  static const int numThreads(100);
  std::thread t[numThreads];
  for (int i = 0; i < numThreads; ++i)
    t[i] = std::thread(boostThread, _path);
  for (int i = 0; i < numThreads; ++i)
    t[i].join();
  std::cout << "Boost result: " << boostResult << std::endl;
  return boostResult;
}

I did 5 runs and had between 8 and 14 failures each time.

version Boost 1.60.0 → Boost 1.64.0

And the code is the same in 1.67 as well.

Boost C++ Libraries: Ticket #11873: boost::filesystem does not work on windows when multiple processes access the same junction (directory)
