--- Comment #2 from Fujii Hironori <Hironori.Fujii at sony.com> ---
I can reproduce with a following command.

> python ./Tools/Scripts/run-webkit-tests --debug --wincairo --dump-render-tree --no-new-test-results --no-retry-failures --no-timeout  css1/basic/class_as_selector.html

It never exit this loop.
