            Bug ID: 172263
           Summary: AudioSourceProviderAVFObjC::m_tap member access is not
                    thread safe.
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebCore Misc.
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: pvollan at apple.com

It it possible that the main thread will modify the m_tap member by calling AudioSourceProviderAVFObjC::destroyMix(), while m_tap is being read on a secondary thread in AudioSourceProviderAVFObjC::process().
