+Recent regression: segfault on startup with -snapshot
+
+As of git revision 041ccc922ee474693a2869d4e3b59e920c739bc0, qemu segfaults on startup when I try to boot a hard disk image with the -snapshot option.
+
+To reproduce:
+
+  wget http://wiki.qemu.org/download/linux-0.2.img.bz2
+  bunzip2 linux-0.2.img.bz2 
+  qemu-system-i386 -hda linux-0.2.img -snapshot
+
+When I run this, qemu-system-i386 crashes with a segmentation fault. This is on a Debian 7 amd64 host.
+
+git bisect implicates the following commit:

+    complex VFIO data structures that are modified in instance_finalize.
+    Take a shortcut for now.
