1.30.0 - problem with filesystem lib

Hi, When using the filesystem lib in the 1.30.0 release, I experience hangs when incrementing the directory iterator. The compiler I've been using is MinGW, an example that exhibits the behaviour on my machine is included below. The hang only occurs when -mthreads is used. The hang occurs on the increment when there are no more files in the directory.
