OK, so it looks like in CURRENT, at least for the devel/libvirt port,
the gdb in base, and also gdb in ports cannot debug libvirtd.core.
I enabled WITH_LLDB=yes in /etc/src.conf and recompiled
to install lldb. I am not so familiar with lldb, but at least I can
get a stacktrace with it.
lldb /usr/local/sbin/libvirtd libvirtd.core
