Summary: REGRESSION (r130584): Crashes in
JSC::MarkedAllocator::allocateSlowCase, failing
fast/dom/gc-dom-tree-lifetime.html
Product: WebKit
Version: 528+ (Nightly build)
Platform: Unspecified
OS/Version: Unspecified
Status: NEW
Severity: Normal
Priority: P2
Component: Tools / Tests
AssignedTo: webkit-unassigned at lists.webkit.org
ReportedBy: zandobersek at gmail.com
CC: ggaren at apple.com, barraclough at apple.com
The following tests started to crash after r130584
http://trac.webkit.org/changeset/130584
fast/events/drag-link.html
fast/events/crash-on-mutate-during-drop.html
fast/lists/drag-into-marker.html
editing/pasteboard/drag-drop-list.html

editing/selection/4895428-4.html
editing/selection/contains-boundaries.html
svg/custom/use-animation-in-fill.html
svg/custom/use-multiple-on-nested-disallowed-font.html
The list may not be complete. The tests are mostly crashing on the GTK 64-bit debug builder, but there are crashes on Apple's Lion and MountainLion WK2 Debug builders as well.
Here's the long link to the flakiness dashboard for all these tests:

Another regression of this commit is the failing fast/dom/gc-dom-tree-lifetime.html test on GTK and Chromium platforms
http://test-results.appspot.com/dashboards/flakiness_dashboard.html#group=%40ToT%20-%20webkit.org&tests=fast%2Fdom%2Fgc-dom-tree-lifetime.html
The diff shows 6 of these failure messages (the complete diff is too big to paste):
+FAIL <div> objects in a DOM tree are not destructed.
