In function : void LoadConstants(LoadState* S, Proto* f)
If the constant is string, it will be call setsvalue2n .
case LUA_TSTRING:
setsvalue2n(S->L,o,LoadString(S));
and setsvalue2n crashes if LoadString(S) return NULL.
I think if we check the return value of LoadString here would be better :
case LUA_TSTRING: {
TString * s = LoadString(S);
if (s) {
setsvalue2n(S->L,o,s);
} else {
setnilvalue(o);
}
break;
}
