You are not alone with this problem.  I think jmmv is working on a new
version which should make debugging failed tests easier.  Hurry up,

Not really relevant to this list, but: I know there's still some race
in rename, but I've never seen it fail with a segfault.  If you can
reproduce it outside of atf and get a good trace, contact me off-list.
