I'm on Win-10 with the same 7.01 SVN version and it works here.Try adding your IP source-address and see if that make a difference:

nmap -S a.b.c.d -p 1-65535 -T4 -A -v 185.87.49.223

@billionaire I can't see what would be causing this. Can you reduce the crash to a smaller number of scan options? For example, try nmap -T4 -sC -d --script-trace 185.87.49.223 to eliminate the version scan, OS detection, and traceroute, while adding some diagnostic output that could narrow in on one script in particular causing the problems.

Hi,

I have the same error (?), the script stops after this warning. I do have another query running though.

nmap -T4 -O -A -v www.bluecape.nl

@timvanderweijde Thanks for bumping this issue. Found a fix, but also found another bug that affects scanning that target. See #378 for why SSL stuff won't work right on POP3, IMAP, etc. there.

Fixed in f38b959

@dmiller-nmap You're welcome. :-) And nice to see the fix already.
