What steps will reproduce the bug?

Hi,

I would like to report a bug, it can be reproduced by running the PoC below:

const {exec} = require('child_process');

Object.defineProperty(Array.prototype, "2", {
  set: function () {},
});

(async function () {
  exec('pwd', (err, stdout, stderr) => {
    console.log(stdout);
  });
})();

Regards,

AH

How often does it reproduce? Is there a required condition?

It reproduces anytime by simply running the given PoC on the given Node.js version.

What is the expected behavior? Why is that the expected behavior?

It is a crash.

What do you see instead?

Commencez par exécuter le PoC JavaScript avec child_process.exec sur Node.js v23.6.0 et confirmez l’erreur fatale. Suivez le chemin de child_process exec impliqué dans le plantage ; le travail est terminé lorsque la reproduction ne se termine plus par « v8::ToLocalChecked Empty MaybeLocal » et qu’un test de régression couvre le PoC.
