qemu-kvm upstream segfaults when using -smp 1

Hi folks:

Today's upstream qemu-kvm.git is crashing when attempting to use -smp 1:

03/04 12:56:12 DEBUG| kvm_vm:0461| Running qemu command:

I have opened a bug about it on KVM's bug tracking system on sourceforge. Relevant software versions involved:

Commit hash for git://git.kernel.org/pub/scm/virt/kvm/qemu-kvm.git is 7811d4e8ec057d25db68f900be1f09a142faca49 (tag kvm-88-3686-g7811d4e)

Please let me know if you need more information about it.
