Hello, I'm writing a C++ application. I realized that one of my worker threads may terminate unexpectedly. The (VS 2005) debug log says:

The thread 'Win32 Thread' (0x5d98) has exited with code -858993460 (0xcccccccc).

I surrounded all the worker thread code with a try/catch block. So, if the reason was an exception, I would catch it. But I can't:

try{
   ...
   Connection* conn = connectionPool->getConnection(); // unexpected exit occurs here
   ...
} catch(exception& e) {
   ...
}

I have ten threads running concurrently, and only one of them gets crashed after some time, while the others continue running (and getting new [OCCI] connections).

Is there an exception type that is not caught by "exception"? Or what do I not know about threads/exceptions?

Thanks.
