Buffer() deprecation check throws TypeError: Cannot read properties of null (reading '0') inside new Promise() #54296

Description

@hyrious

Version

First seen in v20.15; No issue in v20.14

Platform

Microsoft Windows NT 10.0.19045.0 x64

Subsystem

No response

What steps will reproduce the bug?

Just create a file and run:

new Promise(() => {
  new Buffer(0)
})

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

It requires Node.js ≥ v20.15. Node.js v20.14 is working fine.

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

It should not throw.

What do you see instead?

node:internal/util:508
        filename[0] !== '/' &&
                ^

Additional information

The error occurs only when inside the callback of new Promise(). I looked at devtools and it says one item inside the stack has getFileName()null.
