I have a slightly modified version of Alien.  It runs your sample fine.  
Among other fixes, it has this in core.c:

static int alien_function_gc(lua_State *L) {
 alien_Function *af = alien_checkfunction(L, 1);
 if(af->name) free(af->name);
 if(af->params) {
   free(af->params);
   if(af->ffi_params) free(af->ffi_params);
 }
 return 0;
}

The rest of my fixes can be found at 
svn://svn.luaplus.org/LuaPlus/work51/Src/Modules/alien/src/core.c and 
struct.c.

It is garbage collected.
