Hi Stephan, I was solving the same problem some time ago. The trick is to call the object "destructor" from the deallocator method. You can use e.g. std::shared_ptr with reference counting to relay the actual destruction when both your application and ZMQ are done with the "object". Note that the deallocator method has additional "hint" parameter, which you can use for this.
