Nmap Development: Segfault with large exclude list

Segfault with large exclude list

From: Kurt Grutzmacher <grutz_at_jingojango.net>

Yes this isn't the most efficient way to do a scan but it's not for
business, just for fun. Using superduper 3.83_DC1 release.

./nmap -sV -sS -PS:80 -R -p 80 172.16.0.0/14 -v -v -T2 --randomize_hosts -oA ../everybody_dance --scan_delay 500 --max_hostgroup 2 --excludefile ../scanned_1 -d -d -d -d

[... lots of stuff ...]
doing 0.0.0.0 = 172.16.116.2
doing 0.0.0.0 = 172.16.116.209
doing 0.0.0.0 = 172.16.126.204
doing 0.0.0.0 = 172.16.0.19
doing 0.0.0.0 = 172.16.7.31
Segmentation fault
