Verified using attached program on Windows 8.1 and Windows Server 2012. The problem occurs because when the current path is a directory symlink then boost::filesystem::is_symlink(path(""c:"")) returns true. Assuming the following paths: myDir = c:\temp\symlink-example\dir mySym = c:\temp\symlink-example\sym -> myDir myFile = c:\temp\symlink-example\dir\hello.txt When current path is set to mySym and canonical(myFile) is called: * The path components of myFile are iterated over (operations.cpp:827) * ""c:"" is the first component. It is considered a symlink and expanded (operations.cpp:844) * The path then becomes c:\temp\symlink-example\dir\temp\symlink-example\dir\hello.txt * scan is set true and the loop repeats. ""c:"" is again expanded. The loop repeats infinitely as the path grows longer and longer " Bugs new To Be Determined filesystem Boost 1.60.0 Problem
