            Bug ID: 230140
           Summary: Use of memcpy with overlapping memory pointers
           Product: WebKit
           Version: Other
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Keywords: InRadar
          Severity: Normal
          Priority: P2
         Component: Media
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: jean-yves.avenard at apple.com

Problem introduced in bug 229251; the memory buffer content is shifted to the left; the use of memcpy under these circumstances is fine. But it triggers Asan "AddressSanitizer detected: memcpy-param-overlap"

Should change memcpy to memmove here to keep asan happy.
