Yep, that makes sense. I modeled this on 219 which was using
$here/src/lstat64 but didn't think about the fact that in my test fsgqa
might have traversal problems. I see plenty of other tests are using
relative paths so the following patch should (hopefully) fix 317 for you.
Thanks for tracking it down.
