So WRD, I'm here to spoonfeed you yet again.

While reversing the next update, I noticed a change in the vm (not all other arith).

OP_ADD has the registers offset by some trash constants, I'm in disbelief that these will change according to future updates, however I'll release my fix today, on the next update if you run the following script you should crash.

 

print((5 + 4) + 10)

As for my fix, it's quite simple, go to lcode.c and find the constfolding function.

for the first couple lines, simply paste and replace this before the case OP_SUB:

 

    lua_Number v1, v2, r;
    if (!isnumeral(e1) || !isnumeral(e2)) return 0;
    v1 = e1->u.nval;
    v2 = e2->u.nval;
    switch (op) {
    case OP_ADD: 
        if (v1 * 2 == 18.0 && v2 * 6 == 60.0)
        {
            r = 50 % (int)v1 + 16;
            break;
        }

        r = luai_numadd(v1, v2);
    	break;

Once you've done that you're finished, the next update should not cause any issues with addition airth, if this happens for any other arith operations I'll post as well.
