Subsystem

What steps will reproduce the bug?

const assert = require('assert')

process.exitCode = 2
delete process.exitCode // REMOVE
assert(process.exitCode === undefined) // REMOVE
process.exit(undefined)

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

reproduces on all node versions built after landing #44711

What is the expected behavior?

the assertion should pass, and if the two lines marked REMOVE are commented out the process should exit with code 2

What do you see instead?

the assertion throws, and if the two lines marked REMOVE are commented out the process exits with code 0

Bắt đầu bằng cách chạy bản tái hiện trên một bản build sau #44711 và so sánh việc xóa process.exitCode với process.exit(undefined). Hoàn tất khi assertion đạt và tiến trình vẫn thoát với mã 2 khi các dòng được đánh dấu bị xóa.
