It was thus said that the Great Luiz Henrique de Figueiredo once stated:

32 bit Linux, Lua 5.1.4 (with all the patches [1]) and the following C
code:
#include <stdio.h>
#include <lua.h>
static int construct(lua_State *L)
{
int stack_size;
stack_size = lua_gettop(L);
printf("construct %d items in stack\n",stack_size);
lua_pushinteger(L,stack_size);
return 1;
}
int luaopen_construct(lua_State *L)
{
lua_register(L,"construct",construct);
return 0;
}
