I can reproduce this with build:
libvirt-1.1.1-9.el7 

verify with build:
libvirt-1.1.1-10.el7 

step:
 write a c file to test this:
 add below in file:
....
  callback1ret = virConnectDomainEventRegisterAny(conn,
                                                    dom1,
                                                    VIR_DOMAIN_EVENT_ID_REBOOT,
                                                    VIR_DOMAIN_EVENT_CALLBACK(myDomainEventCallback2),
                                                    strdup("cb1"), myFreeFunc);
....

#gcc test.c -o test -lvirt
