Comment 1 Ryosuke Niwa 2013-02-18 23:43:11 PST 
Added a failing test expectation in http://trac.webkit.org/changeset/143291.
Comment 2 Alexey Proskuryakov 2013-09-27 14:10:48 PDT 
This code was all rewritten, and the test now just fails. That's tracked as bug 122021, so closing this bug as obsolete.

Removed old Pass/Crash entry from ChangeLog in r156572, as it was confusing the parser, making it ignore the new Skip one.
