Comment (by randydu@…):

 It also happens on Mac.

 The problem is:

 path dir("foo/");
 dir.parent_path() ==> "foo";  (not "")

 hence when create_directories() is called, according to the current
 implementation (operations.cpp), the parent_path is created ("foo") first,
 then create_directory("foo/") is called and returns FALSE with an error
 (BOOST_ERROR_ALREADY_EXISTS).

 If the trailing slash is removed:

 path dir("foo");
 dir.parent_path() ==> "";  (now empty: "")

 then everything works perfectly.


 So the bug fix is creating a public wrapper of create_directories() to
 remove trailing slash of input parameter before calling internal
 create_directories().

 Thanks,
 Randy
