Bug using Lua 5.2.0 in VS2005

[John Tan <johnmave126@...>]

The following codes could perform the bug

//C Source Code

#include "lua.hpp"

int f1(lua_State *L) {

printf("%d\n", lua_tonumber(L, 1));

return 0;

}

int main (int argc, char* argv[]) {

lua_State *L = luaL_newstate();

luaL_openlibs(L);

lua_pushcfunction(L, f1);

lua_setglobal(L, "f1");

lua_getglobal(L, "f1");

lua_pushnumber(L, 1);

lua_call(L, 1, 0);

return 0;

}

After executing it,f1 will print 0 on the screen which indicates that it gets nil on stack when it is called.

I don't know if there is anybody else meeting the same problem...

Hope to know what has happened...THX
