Apart from (probably) slowing things down, you're just shadowing
a bug then! That's generally considered a regression. I'd rather
have an error thrown. Something like:

static int staticcheck;

LUA_API void lua_checkconsistency(lua_State *L, int vernum)
{
  if (vernum != LUA_VERSION_NUM || G(L)->staticcheck != &staticcheck)
    luaG_runerror("...");
}

This should be called from strategic places, e.g. luaL_openlibs(),
luaL_register() and maybe some more.
