Right, this is a double free, Eric, Hasn't Coverity found this issue?
It's not a double free, since the first VIR_FREE sets buf to NULL, making the second one a no-op, which is why Coverity won't warn about it. -- Eric Blake eblake@redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org
