This error is made at run-time. From the stack, FeatureReply DTOR is called. >From there, of10::Port DTOR is called and subsequently Port Common is called. When PortCommon is called , it gives error.

I can provide more details. Bit complex to reproduce the issue. Otherwise, I can do some test here if you propose.
