Follow up from my previous comments... I think the problem is related to the use of virEventRegisterDefaultImpl() in libvirt_cim_init(), which is called by all providers, not just indication providers. Given the number of times we call that function, perhaps we're overloading libvirt and/or triggering an underlying bug. When I either comment out that function, I see no crashes. I then moved it to be called once in ComputerSystemIndication->ActivateFilter() (via a static init variable), and I was able to avoid the crashes. Unfortunately, I'm not able to verify the domain events function via cimtest. FWIW, I see the same message w/o the patch so perhaps I need to do something else to make it work.
