            Bug ID: 241559
           Summary: The extraMemorySize() get wrong when transferring
                    ArrayBuffer from Worker VM
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: Basuke.Suzuki at sony.com

When ArrayBuffer is passed in the transfer option of postMessage(), the size cached in heap.m_arrayBuffers get incorrect and that makes extraMemorySize() bigger than actual managed size.
