The following layout test is failing on GTK, only on Release
Started failing in r152319
Actually, the test started failing was in http://trac.webkit.org/changeset/152320, when there was some refactoring for the CSS Regions support.
It reports that "<div> objects in a DOM tree are not destructed.", since the number of live nodes after the garbage collection is not decreased at least in 9.
However, I don't understand how GTK in Release is the only configuration affected. Besides, if I add prints in InspectorCounters::counterValue, then the garbage collection seems to work, and the number of live nodes is correctly decreased.
I don't plan to continue working on this, at least for some time, so feel free to grab.
This test is passing now, both in the bot and locally, so the issue is apparently fixed.
Test expectation will be updated accordingly.
Simon, please confirm and close.
