Bcc:

How so? The TCP/IP stacks should take care to never try this.

Well, actually, TCP/IP stacks are fine, I faced this problem when I use vnc_server package. It does cause problem on my target. So I have to modify it. See patch please.

This is a well known problem on ARM; such operations are undefined (some
chips/cores
may throw an exception, but in general they just quietly do the wrong
thing). The only
real solution is to just not try to perform unaligned operations of this
sort.

Ok, got it!
