SEGV in function ControlObjectClient_setCommandTerminationHandler

[fouzhe]

I used gcc 5.4 and AddressSanitizer(export CFLAGS="-g -fsanitize=address" CXXFLAGS="-g -fsanitize=address" LDFLAGS="-fsanitize=address" before make) to build libiec61850.

First, I run the server_example_basic_io in directory libiec61850/examples/server_example_basic_io by command sudo ./server_example_basic_io so that the server is set up. Then I tested iec61850_client_example_control in directory libiec61850/examples/iec61850_client_example_control by command sudo ./client_example_control. But I got SEGV in function ControlObjectClient_setCommandTerminationHandler in client_control.c.

This is the ASAN information:

The example cannot run with server_example_basic_io. It is intended to be run with server_example_control that has the required data model to show the usage of advanced control models.
