Description Sudish Joseph 2001-05-30 10:40:01 UTC 
/usr/sbin/ppp attempts unaligned accesses when resolving dns queries.
On an alpha this can and does cause a core dump.  The patch below removes
the unaligned access.

Fix: The following patch replaces the unaligned access with a bcopy(), which
fixes the problem.
How-To-Repeat: Run /usr/bin/ppp on an alpha and do anything that causes ppp to do dns
lookups.  For instance, try a traceroute without -n.  Given the right 
dns reply packet -- one with unaligned data -- ppp dumps core.
