[libvirt] virConnectClose() sometimes seg faults libvirt 0.7.0
Hi,
I'm trying to track down a seg fault I'm seeing with the
libvirt-0.7.0-3.fc12.x86_64 rawhide version of libvirt.
I'm having trouble finding the exact set of steps, as I see the behavior
when interacting with the libvirt-cim providers.
Here's the stack trace I was able to get. Looks like the seg fault
actually occurs in netcf, which I haven't looked at much. Has anyone
seen this?
Program received signal SIGSEGV, Segmentation fault.
