    Unwind the stack on error, to get the full path that led to the illegal
    access. Example of output:

    kASan: Unauthorized Access In 0xffffffff80e6219c: Addr 0xffffbb007a39fd03 [1 byte, read]
    #0 0xffffffff80e6219c in ras_purgeall <netbsd>
    #1 0xffffffff80e62330 in sys_rasctl <netbsd>
    #2 0xffffffff80265008 in syscall <netbsd>

    (I manually added a one-byte stack read overflow in rasctl to demonstrate.)
