This appears to be caused by the early return in fs::_Dir's ctor:
_Dir(const fs::path& p, bool skip_permission_denied, bool nofollow,
[[maybe_unused]] bool filename_only, error_code& ec)
: _Dir_base(p.c_str(), skip_permission_denied, nofollow, ec)
{
#if _GLIBCXX_HAVE_DIRFD // && 0
if (filename_only)
return; // Do not store path p when we aren't going to use it.
#endif
if (!ec)
path = p;
}
but somehow disabling the early return to force the saving of path
appears to break copy(): copy.cc's test01() succeeded without the '&& 0'
that I've commented-out above, but started failing to create 'to' in the
copy at line copy.cc:54 when I put it in to prevent the early return.
Does that make any sense to you?
