Rest arguement is mishandled when controlFlowFlattening is enabled #920
Description
Expected Behavior
Expected output:
function f(e, h, i, j) {
console['log'](e, h, i, j);
}
function g(...b) {
const c = {
'vtpEA': function (d, ...e) {
return d(...e);
}
};
c['vtpEA'](f, ...b, 0x5);
}
const a = [
0x1,
0x2,
0x3
];
g(...a, 0x4);
Current Behavior
Current output:
function f(e, h, i, j) {
console['log'](e, h, i, j);
}
function g(...b) {
const c = {
'vtpEA': function (d, ...e, h) {
return d(...e, h);
}
};
c['vtpEA'](f, ...b, 0x5);
}
const a = [
0x1,
0x2,
0x3
];
g(...a, 0x4);

Stack trace
Minimal working example that will help to reproduce issue
function f(a, b, c, d) {
console.log(a, b, c, d)
}
function g(...args) {
f(...args, 5)
}
const a = [1, 2, 3]
g(...a, 4)
