Access violation using ofxFlashCommunication

I’m using ofxFlashCommunication by roxlu. It’s a great addon. Messaging between flash application works good.

However, when I terminate an oF application using ofxFlashCommunication, 0xC0000005 access violation occurs.
It seems that Poco used in ofxFlashCommunication has something wrong.

Anybody knows this issue and its solution?

Thanks in advance.
