Well, let us just say I'm glad I decided to run ALPHA releases by you
guys before the big stable release.  Arturo "Buanzo" Busleiman
(buanzo(a)buanzo.com.ar) has already found a way to segfault
3.59ALPHA1 by scanning certain machines with connect() scan.  This
scan type is normally only used by non-root users.  I have released
version 3.59ALPHA2, which should fix the problem:


This is from a syn scan...

# /usr/local/nmap.a/bin/nmap -sS -P0 -p '1-65535' -T 4 -vv host.example.org
