What steps will reproduce the bug?

const test = async function (b1) { b1 = Buffer.concat([b1, Buffer.from('\n')]) b1 = Buffer.concat([b1, Buffer.from('\n')]) b1 = Buffer.concat([b1, Buffer.from('\n')]) b1 = Buffer.concat([b1, Buffer.from('\n')]) return b1 } const test2 = async () => { let b1 = Buffer.alloc(1024 1024 300, '1') console.log(b1.length) b1 = await test(b1) console.log(b1.length) } test2()

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

Most time

What is the expected behavior?

Run successfully and print 314572800 314572804

What do you see instead?

UnhandledPromiseRejectionWarning: RangeError: Array buffer allocation failed at new ArrayBuffer () at new Uint8Array () at new FastBuffer (internal/buffer.js:951:1) at createUnsafeBuffer (buffer.js:152:12) at allocate (buffer.js:422:10) at Function.allocUnsafe (buffer.js:387:10) at Function.concat (buffer.js:567:25) at test (C:\Users\fluentwind\WebstormProjects\esign\test\testBuffer.js:3:15) at test2 (C:\Users\fluentwind\WebstormProjects\esign\test\testBuffer.js:11:14) at Object. (C:\Users\fluentwind\WebstormProjects\esign\test\testBuffer.js:14:1)

Additional information

I want to concat a buffer and get a full buffer.

But memory usage never goes down. Is there anything wrong with gc?
