What steps will reproduce the bug?
const vm = require("vm");
let impl = { status: "" };
let ctx = vm.createContext();
Object.defineProperty(ctx, "status", {
configurable: true,
enumerable: true,
get() {
return impl.status;
},
set(v) {
impl.status = `${v}`;
}
});

vm.runInContext(`

console.log(args.map(JSON.stringify).join("\t"));
}

`, ctx);How often does it reproduce? Is there a required condition?
Always.
What is the expected behavior?
The functions get defined using [[DefineOwnProperty]] as specified in ECMA‑262 § 8.1.1.4.18 CreateGlobalFunctionBinding.
