Seems to me that a simpler (and more correct) patch would be to
change lbaselib.c:121
from:
int level = luaL_optint(L, 1, 1);

int level = luaL_checkint(L, 1);
That was my first thought, but then the error message is misleading
(that it expected a number).

Yeah, I'd normally write something like:
switch (lua_type(L, 1)) {
case LUA_TFUNCTION: {
// handle the function case
}
case LUA_TNUMBER: {
int level = lua_tointeger(L, 1);
// ...
}
default: luaL_typerror(L, 1, "number or function");
}
