Nmap 6 bug: get_srcaddr

[Martin Clausen <MCL () danskebank dk>]

Hi

So I just upgraded to Nmap 6. While testing I ran into this little 
problem:

C:\Temp\server-lans>nmap -T3 -sn 10.80.0.0/16 -dd -vv

Starting Nmap 6.00 ( http://nmap.org ) at 2012-05-23 10:30 Romance 
Daylight Time
Winpcap present, dynamic linked to: WinPcap version 4.1.2 (packet.dll 
version 4.1.0.2001), based on libpcap version 1.0 branch 1_0_rel0b 
(20091008)
NPF service is already running.
Fetchfile found C:\Program Files\Nmap/nmap.xsl
The max # of sockets we are using is: 0

  max-scan-delay: TCP 1000, UDP 1000, SCTP 1000
  parallelism: min 0, max 0
  max-retries: 10, host-timeout: 0

---------------------------------------------
get_srcaddr: can't connect socket: The requested address is not valid in 
its context.
nexthost: failed to determine route to 10.80.0.0
QUITTING!

However, there is connectivity to 10.80.0.0/16, e.g.:

C:\Temp\server-lans>ping 10.80.0.21

Pinging 10.80.0.21 with 32 bytes of data:

Reply from 10.80.0.21: bytes=32 time=23ms TTL=124

Ping statistics for 10.80.0.21:
    Packets: Sent = 1, Received = 1, Lost = 0 (0% loss),
