I also get a panic in this case running a current kernel (ELF, and since dg's recent changes in this area). Mine however dies with (from memory): vm_object_terminate: not freeing wired page; wire_count=1 which is something dg changed the other day. I havent yet been able to get a core dump - something odd is going on where it says it's dumping an image, but doesnt seem to. I was planning on looking at this further since I've probably done something wrong (can you in fact dump to a vn which is configured as a swap device? I don't have big enough "real" swap partitions to take a kernel dump), but since it's come up..
