Then I will need a little help, please: can you debug what happens
when patch tries to traverse_path() "dir/foo/bar"? It should try to
openat() subdirectory "foo" in "dir", the openat() should fail with
errno == ELOOP, and patch should terminate. But maybe FreeBSD returns
some other errno like ENOTDIR.

Maybe it's as simple as the attached patch.

Thanks,
Andreas
