Looks like r9 and r14 have the same odd value. Normally I would see a more obvious breakage such as one of the 'f' nibbles being set to '0' or 'e', etc. You could try looking for that odd pointer value in the route structure or as arguments to other functions in the stack trace to see if you can find a corrupted data structure. -- John Baldwin
