### Version
v16.17.0
### Platform
Linux 5.15.0-46-generic 49~20.04.1-Ubuntu SMP x86_64 x86_64 x86_64 GNU/Linux
### Subsystem
_No response_
### What steps will reproduce the bug?
The following script causes a segmentation fault
```js
const inspector = require('inspector');
const session = new inspector.Session();
session.connect();
session.post('HeapProfiler.enable', () => {
session.on('HeapProfiler.addHeapSnapshotChunk', (message) => {
console.log(message);
});
session.post('HeapProfiler.takeHeapSnapshot', { reportProgress: true }, (err, result) => {
console.log(result);
});
});
```
### How often does it reproduce? Is there a required condition?
The bug happens every time the script is run, tested on multiple Linux machines.
### What is the expected behavior?
It is expected that node logs the result of the heap snapshot
### What do you see instead?
[1] 1152371 segmentation fault (core dumped) node segfault.js
### Additional information
The bug seems to appear with Node v16 and is also present in Node v18, works fine with Node v14
This only happens when setting `reportProgress: true` flag when taking the heap snapshot with `HeapProfiler.takeHeapSnapshot`
Here is the stacktrace when the segfault occurs
