I can only guess, but my guess is that either you haven't got a 
consistent build environment. For example, you might have built your 
app with USE_LONG, but with a library compiled with normal doubles. Or 
you might have built the library with USE_LONG, but not defined 
LUA_NUMBER before you #include <lua.h> in your application. Or some 
variation on those themes.
