           Summary: ThreadingWin: Mutex::unlock() can be "over-unlocked".
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2

        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: jer.noble at apple.com


Unlocking a Mutex more times than it's m_recursionCount will result in the m_recursionCount wrapping around to MAX_INT.  There should be at least an ASSERT(m_recursionCount) in Mutex::unlock(), if not an explicit: "if (m_recursionCount) --resursionCount;"
