           Product: WebKit

          Platform: Macintosh
        OS/Version: Mac OS X 10.5
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2

        AssignedTo: webkit-unassigned at lists.webkit.org

Calculation of the storage size for the vector portion of the array can
overflow, leading to insufficient memory being allocated.  Limit vector length
to prevent overflow.
