Description

Hi there. I didn't write on e-mail this time, because that just a bug report (ONE MORE KRUZYA :D)
So, I try obfuscate some code. I use plural-ru, but I think this isn't trouble of plural-ru package.

So, in short description. If I right, obfuscator with next config:

{
    "controlFlowFlattening": true,
    "controlFlowFlatteningThreshold": 1.0,
}

Just lose a few arguments by spread operator. For more check examples.

Steps to reproduce

1. Create function with spread operator (...some_array).
2. Obfuscate with my settings.
3. Profit.

Examples

Oh shit, here we go again...

Original:

// index.js | Я упростил код до 2 + 2. 
const plural = require("plural-ru");
const translate = ["Kruzya", "Is", "P..."];
plural(online, ...translate); // in this line I found bug, but go next...

Obfuscated:

_0x102640['HrGnp'](plural, online, ...translate); 

Function:

How you can see, function can send only 3 arguments.

• first: plural,
• second: online,
• third: array.

But in third argument we have a bug ... because ...translate => arg1,arg2,arg3, ..., argn (n = length of array).
So, here we get 5 arguments, but sended only 3.

Result of this exec:

This is a potential bug of obfuscator 👀
