Comment (by wdormann):

 I shared a list of the filenames from my (problematic) system above.
 Do you need an actual tarball of the directory?

 {{{
 $ find c++/
 c++/
 c++/v1
 c++/v1/experimental
 c++/v1/experimental/any
 c++/v1/experimental/chrono
 c++/v1/experimental/numeric
 c++/v1/experimental/optional
 c++/v1/experimental/ratio
 c++/v1/experimental/string_view
 c++/v1/experimental/system_error
 c++/v1/experimental/tuple
 c++/v1/__cxx_version
 c++/v1/__functional_03
