           Summary: ASSERT in WebCore::RenderTableCell::styleDidChange
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Layout and Rendering
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: falken at chromium.org
                CC: jchaffraix at webkit.org


This assert is hit sometimes on fast/table/table-cell-before-after-content-around-table-row.html for Chromium Mac10.6 (dbg):

http://test-results.appspot.com/dashboards/flakiness_dashboard.html#group=%40ToT%20-%20chromium.org&tests=fast%2Ftable%2Ftable-cell-before-after-content-around-table-row.html

I'm not sure if it's a recent regression. The dashboard data goes back to the beginning of this week, and the crash occurred then. Possibly related to bug 78695.
