No, that's bug 21341 (if indeed the problem was the regex, the submitter
of the patch which changed the regex didn't mention the bug and its prior
change from PASS to FAIL). There are multiple test assertions within the
same test file, and when any one changes from PASS to FAIL that is in
principle, and in practice in this case, a separate bug.
