      Strange bug : When using QUdpSocket bind() , it prevents other third-party DLL  dllMain DLL_PROCESS_DETACH  entry point to be called when process exit.

      NO problem if  QUdpSocket ::bind() line is commented.

      Note that using native Windows UDP API bind() do not show the problem.

      Test case joined ( .zip ) with a simple (void) DLL   and a simple QT app using this DLL .
