I don't know what kind of test you have in mind, so I added a runtime test. I

that's the goal.
Yes, a runtime test. I don't think there should be an xfail without it
actually having been tested to fail (and then such an xfail should come
with a comment referencing the bug filed in Bugzilla).
Would it be ok with the attached testcase then? (same ChangeLog).
