This look like the same problem as #5649, but the consequences are more serious I think. Some people put the temp directory on a mounted volume, and in this case temp_directory_path() fails although windows has a valid temporary directory. I use some commercial software that uses temp_directory_path() which will fail without useful error messages." Bugs new To Be Determined filesystem Boost 1.54.0 Problem
