for (i = 0; i < (1UL << 24); i++) {
      void *ptr;
      ptr = lua_newuserdata(L, 4096);
      luaL_setmetatable(L, "mt");
      ref = luaL_ref(L, 1);
      luaL_unref(L, 1, ref);
   }

I may be misunderstanding but ... Don't you just keep creating
userdata and filling up the Lua stack? There's no lua_pop or similar.
luaL_unref [-0, +0, -] only unrefs the object, but doesn't pop it.

Best regards,
