Excellent.  I got a crash (no error message) today testing a -PA -sP
scan with your migrated mass-ping against the old code.  I wasn't able to
run -d because of the extreme verbosity and Kris beat me to the note about
turning it down.

Here are the results of today's preliminary test:

I ran two scans:

time ./nmap -n -v -PA135,139,445,3389 -sP --min-hostgroup 2048 -oA
~/oldping a.b.0.0/16 c.d.0.0/16 e.f.0.0/16

and

time ./nmap -n -v -PA135,139,445,3389 -sP --min-hostgroup 2048 -oA
~/newping a.b.0.0/16 c.d.0.0/16 e.f.0.0/16

This is the typical Windows host discovery scan I do every few days to find
hosts that I then go do a 64k port scan of.

The oldping scan produced this at the end:

Host e.f.255.255 appears to be down.
Read data files from: .
Nmap finished: 186336 IP addresses (13293 hosts up) scanned in 1336.978
seconds

real    22m16.992s
user    0m7.834s
sys     0m39.758s

$ echo $?
0


The newping scan produced this at the end:

Host c.d.200.31 appears to be down.
Initiating Ping Scan at 00:14
Scanning 2048 hosts [4 ports/host]
Ping Scan Timing: About 7.76% done; ETC: 00:20 (0:05:57 remaining)


real    83m39.999s
user    11m47.630s
sys     1m25.964s

$ echo $?
130


Without debugging output I don't have anything else for you yet.

I'm firing off both scans again this time with -d so hopefully in ~83
minutes I'll have results.
