It appears attribute nodes are being garbage collected too aggressively. 717513 1 dominicc 2012-09-11 13:43:52 -0700 *** Bug 88062 has been marked as a duplicate of this bug. *** 1002483 2 ap 2014-04-20 22:59:01 -0700 *** Bug 131881 has been marked as a duplicate of this bug. *** 1002485 3 ap 2014-04-20 22:59:30 -0700 *** Bug 127480 has been marked as a duplicate of this bug. *** 1002487 4 ap 2014-04-20 23:06:31 -0700 Consolidated test expectations in <http://trac.webkit.org/r167583>. The test for this is fast/dom/gc-attribute-node.html, and it's not a very good test, because it sometimes starts to pass because of memory layout changes. I expect that running the second half of the test asynchronously would make it more reliable, as garbage collection would be more likely to work better.
