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.

[~PortCommon]

(line 28).

These information is not enough. I can provide more details. Bit complex to 
reproduce the issue. Otherwise, I can do some test here if you propose.

Best regards
