Crashes on iMac machine

Title: Crashes on iMac machine

Hi,

Our application creates its own thread using BSD call. It then registers a run loop source (m_hShutdownEvent) with the run loop before starting the run loop. Here is the portion of the code:.

        {
                CSmartCriticalSection cs(&m_hAccessCS);
                               
                m_hCFRunLoop = CFRunLoopGetCurrent();
       
                // Register the shutdown event
                CFRunLoopAddSource(m_hCFRunLoop, m_hShutdownEvent, kCFRunLoopDefaultMode);
        }
       
        // Start the run loop
        CFRunLoopRun();

where m_hShutdownEvent is declared as "CFRunLoopSourceRef m_hShutdownEvent"

The problem is that the program always crashes at CFRunLoopAddSource() call. Occasionally it has luck the first time but gets hit again the second time the code is executed. As far as I know, this problem only occurs on iMac machine.

Am I missing anything?
