If multiple interest filters are set for a same face then calling shutdown() on face may cause a segmentation fault.

To reproduce the error set another test filter in producer.cpp as shown below:

face_.setInterestFilter("/localhop/testApp",
                        bind(&Producer::onInterest, this, _1, _2),
                        bind(&Producer::onRegisterFailed, this, _1, _2));

Then put face_.shutdown() in onInterest case as well to force the shutdown. Otherwise wait for the onRegisterFailed to be called.

Buiild it and run it again:

~$ ./waf && ./build/examples/producer

ERROR: Failed to register prefix in local hub's daemon (Unauthorized command)

 Segmentation fault: 11 (core dumped)

The output from the lldb is attached.
