System: NetBSD oak 1.6I NetBSD 1.6I (oak) #9: Thu Oct 17 18:43:09 UTC 2002 root@oak:/home/src/sys/arch/sparc64/compile/oak sparc64
Architecture: sparc64
Machine: sparc64
>Description:
tcpdump dumps core with a bus error in print-*.c, isoclns for example.
problem is that LBL_ALIGN is not defined (from extract.h) resulting
in an unaligned access.
>How-To-Repeat:
use tcpdump on sparc64 to collect IS-IS PDUs.  tcpdump will most
likely get a bus error.

the value of tptr will be only byte aligned.
>Fix:
define LBL_ALIGN for sparc64.
