Art,

You might check the "limit" command output to
see if the user has different restrictions on
stacksize, datasize etc than the other users.

Another possibility is that the acount is a different
group than the others and that user doesn't have read 
access to the $GEMTBL files that nmap2 needs
(all the directories and fines under $NAWIPS
are packaged world readable, but that could get changed
by the user umask that unpacks the tarfile).

After those checks, it could be that the user has a table in 
his/her directory that is overriding the $GEMTBL location,
and is incorrectly formatted). Can you run via gdb and determine
where the program is when the fault occurs? Have you tried launching
in a different directory as that user?
