Hmm, your %rdx is garbage. :(

rdx            0xef3fdf377db53afa       -1207000745686779142

That should at least be

               0xffffff..........

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.
