I did a quick pass over ip_mroute.c to see if I could have introduced any obvious errors during refactoring; didn't see anything obvious. The backtrace which was posted points towards a trashed rte->m pointer, assuming it's accurate and the arguments didn't get trashed on-stack. The MFC lock should be held in expire_mfc(). I'll add a lock assertion there for now. The VIF lock shouldn't be needed in this path.
