I used
/tmp/file-system-test-ed4fa1/DirNameWith19Chars1/DirNameWith19Chars2/DirNameWith19Chars3/DirNameWith19Chars4/DirNameWith19Chars5/DirNameWith19Chars6/DirNameWith19Chars7/DirNameWith19Chars8/DirNameWith19Chars9/DirNameWith19CharsA/DirNameWith19CharsB/DirNameWith19CharsC/
because with unique names it's easier to see how far down you are.
It doesn't hang for me under Wine, it just fails to remove the directory and
reports a "No such file or directory" error.
That happens in _Dir_base::advance:
const posix::dirent*
advance(bool skip_permission_denied, error_code& ec) noexcept
{
ec.clear();
int err = std::exchange(errno, 0);
const posix::dirent* entp = posix::readdir(dirp);
This readdir call (which uses _wreaddir) fails and sets errno. That's odd
because dirp was opened successfully by opendir. It's probably because we've
exceeded MAX_PATH at this point.
I don't have any good ideas for solving this. I don't really want to chdir into
each sub-directory so that opening the next one can use a relative path (and I
don't even know if that would work any differently).
I also don't want to have to use Windows APIs here.
