in Visual C++ in Debug mode. The isprint, isalpha, etc. functions from ctype.h
have an assertion that the value of the character passed in is <= 255. If you
pass a character whose value is >= 128, it is cast to an unsigned int, making
it a large positive number and failing the assertion. This is the same thing
that was reported in http://seclists.org/nmap-dev/2007/q2/0257.html, in regard
to non-ASCII characters in nmap-mac-prefixes.
struct not being set in any of the pcap functions. Because of this,
the callback routines would attempt to use a NULL pointer for the lua_State *
and would then SEGFAULT.

and --script-trace. It was set at 5, now it's 2. That's enough to see
all the Nsock events and the contents of reads and writes. At 3 you
start to get messages like
PCAP do_actual_pcap_read READ (IOD #%li) (EID #%li) size=%i
The message "wait_for_events" isn't printed until level 4. Getting rid
of that is the main reason for this change.
Moved the includes for Lua headers to the .cc files so they are
not needlessly, repeatedly included.
Similarly, moved some standard headers to the .cc files and reorganized
includes to be uniform for all nse_* source files.
Fixed whitespace (removed tabs).
o Nsock now supports binding to a local address and setting IPv4 options
with nsi_set_localaddr() and nsi_set_ipoptions(), respectively. [Kris]
o Nmap's Nsock-utilizing subsystems (DNS, NSE, version detection) have been
updated to support the -S and --ip-options flags. [Kris]
nse_main and nse_nsock. nse_main now uses Lua to create printable output
while a cleaner hexify procedure has been placed in nsock.
nse_string is removed as a result.
Now does most of it's work through Lua:
From Nmap-dev: "Many of the changes consist of changing how Nmap interfaces
with Lua that were sometimes awkward or inflexible. Most of the functions
have been made to be callable directly by Lua which offers many technical
advantages: stack management is alleviated, errors are handled cleanly and
are more descriptive, and there is increased reusability."
Additionally:
-- Moved all lua_State * symbols from "l" to "L". This is to maintain
consistency with other Lua libraries (convention) and to make our macros portable.
-- Moved file system manipulation over to nse_fs.cc (from nse_init.cc)
