Description

Bug report by Jeremy Jones:

This can be easily reproduced using the following command:

> 0::list int

Error message from kmdb (error in strcmp?):

-------------------------

[1]> 0::list "struct list_node" 

*** Debugger Fault (CPU 1)

    trapno: 13, sp: ffffffffff8cf440, pc: fffffffffbd6c115 strcmp+0x25

    [ 1] ffffff01cd0d4588 ()
    mis-aligned frame (deadbeef0000001c)

kmdb: reboo(t), or (d)ebug with self?

This only seems to happen from "mdb -k".
