> Can you please print pip, *pip, uh, p and nsh in AliasHandleUdpNbtNS()?

(gdb) print pip
$1 = (struct ip *) 0x11feb910
(gdb) print *pip
$2 = {ip_hl = 0, ip_v = 0, ip_tos = 0 '\000', ip_len = 256, ip_id = 256, ip_off = 0, ip_ttl = 0 '\000', ip_p = 0 '\000', ip_sum = 0, ip_src = {s_addr = 0}, ip_dst = {s_addr = 0}}
(gdb) print uh
$3 = (struct udphdr *) 0x0
(gdb) print p
$4 = (u_char *) 0x11feb910 ""
(gdb) print nsh
$5 = (NbtNSHeader *) 0x11feb904
(gdb) print *nsh
$6 = {nametrid = 7168, dir = 1, opcode = 0, nmflags = 0, rcode = 0, qdcount = 256, ancount = 0, nscount = 0, arcount = 0}

After putting in the trap patch i did 'uac -f' and crashed it again.
The only change was a shift, pip -> 0x11feb920 and nsh -> 0x11feb914.

		Hope this helps,
		Rich
