Then I got the following in a windows dialog box with "retry" 
and "ignore"
and "abort", and then I got the "nmap has encountered a 
problem and needs to
close" dialog.


File: isctype.c

Line: 56

Expression: (unsigned)(c + 1) <= 256



Take care,


I ran into this issue a little while ago on my development system (Windows XP SP2 with MS Visual C++ 2005 Express 
Edition), and solved it by switching the build profile from Debug to Release.  If I recall, I think I traced the issue 
to (what I think is) a non-ASCII character in the following line of the nmap-mac-prefixes file:

Line 7040:

001BA1 ├ůmic AB

BTW that line was introduced via SVN rev 4602, which was an update to the latest IEEE data.

You might try removing that line from the file if you still want to run the Debug builds.

Hope this helps,
