nmap bug report, "host down" lines missing on verbose output

[Benjamin Dopplinger <b.dopplinger () gmail com>]

hi

I think I've encountered a bug which occurs if I'm using the -v parameter
(for verbose) in addition with the --scan-delay and --host-timeout
parameters.

I've tried to ping 2 IP addresses which I knew they were unreachable.
If I'm using the -v and --scan-delay parameter nmap behaves as expected and
outputs a [host down] line for each IP address which nmap tried to ping but
was unreachable.
If I'm using the -v and --host-timeout parameter nmap behaves the same way
which is perfectly ok.
But if I'm using the -v, --host-timeout and --scan-delay parameters nmap
suddenly doesn't show the [host down] lines anymore but shows a "2 hosts
timed out" message instead. I expected that nmap would print the [host
down] entries in this case as well.

I've attached a file which includes the output of all three test cases I've
just described.

Can you please have a look into this issue and tell me if this is a bug or
if it is meant to be working like that?

Thank you in advance!

Best regards
Benjamin Dopplinger
