I don't see anything wrong with what you've done from here. Do the
following to see if this helps find the problem:

(1) Configure Nmap with --with-liblua=included. This will make Nmap
statically bind to Lua.

If the problem still occurs, turn Lua assertions on (keeping the above
change for static linking):

(2) Add "-DLUA_USE_APICHECK" to CFLAGS in  nmap/liblua/Makefile.

Lua will catch most common errors this way.
