🐛 bug report

In Node 22.7.0 (not older versions), parcel now fails with this error

pnpm exec parcel build --target html ./src/browser/index.html

💻 Code Sample

https://github.com/aminya/assemblyscript-template/tree/453edd38314835246c692319b6ae53c430a8010f

🌍 Your Environment

Software	Version(s)
Parcel	2.12.0
Node	22.7.0
npm/Yarn	pnpm 9.7
Operating System	KDE Ubuntu 22.04

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

Always

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

There should not be a difference between Node 22.6.0 and 22.7.0

What do you see instead?

Segfault in 22.7.0

I found the function that triggers this error in Nodejs. It seems it was changed last week in a commit to update V8:

nodejs/node@4f1c27a/deps/v8/src/ic/ic.cc#L251 (blame)

This is where the error actually happens: nodejs/node@4f1c27a/deps/v8/src/objects/feedback-vector.cc#L1125 (blame)

Reported it upstream: nodejs/node#54573

Quote from @aminya in the other thread. CC @nodejs/v8

While we wait for them to respond, do you happen to have a reproduction without the use of dependencies like parcel?

If not, could you run the same code with the NODE_DEBUG=* environment variable, and provide the output?

Aug 26 '24 20:08 avivkeller

No, I don't have a simpler reproduction. Parcel also uses Nodejs Add-on API, so @devongovett should be able to help add a reproduction with a debug build of Parcel

Aug 26 '24 21:08 aminya

No worries!

A few things to help narrow this down:

NODE_DEBUG=* will enable debug logging in Node.js, could you try running the same command with that in your environment?
If parcel has a debug logging system, It'd really help to narrow down where this is coming from.

Aug 26 '24 21:08 avivkeller

Here's the log with NODE_DEBUG=*

node ./node_modules/parcel/bin/parcel.js

errors.log

Looks like Parcel's caching code triggers this.

I get errors in v8::internal::StringTable::OffHeapStringHashSet::KeyIsMatch. These occur in multiple different call stacks, e.g. in napi_set_named_property:

Could this be a v8 bug? The stack traces above make me think it isn't specific Parcel's native addons.

It appears that worker_threads may also be involved here. I cannot reproduce when I disable multi-threading in Parcel. Haven't managed to produce a smaller reproduction yet unfortunately...

Aug 31 '24 21:08 devongovett

👋 Hey, v22.8.0 was just released, is this reproducible in that version?

I have same error while building project made with npx create-instantsearch-app

Yes, the parcel builds still fail on Node 22.8.0

Sep 04 '24 21:09 aminya

I can confirm this is reproducible on Node 22.8.

I just got a similar error message with Parcel but on Node 20.17 on macOS:

The stacktraces in https://github.com/nodejs/node/issues/54573#issuecomment-2323042402 seems to suggest that it might be a more generic bug - maybe some kind of memory corruption - but it is difficult to tell what's going on without a minimal reproduction that doesn't use third-party dependencies.

I've reduced at least one of these cases down to a simple reproduction. It requires two typed arrays which are serialized using v8.serialize, and it crashes during v8.deserialize.

let v8 = require('v8');

let data = {
  nodes: new Uint32Array(451),
  edges: new Uint32Array(1155)
};

v8.deserialize(v8.serialize(data));

On macOS with Node v22.9.0 I get:

node(28671,0x1ef3ff240) malloc: Incorrect checksum for freed object 0x134848210: probably modified after being freed.
Corrupt value: 0x0
node(28671,0x1ef3ff240) malloc: *** set a breakpoint in malloc_error_break to debug
Abort trap: 6

If I read this correctly it's SlowCopy that has the problem?

Oct 02 '24 13:10 ronag

Who exactly is calling SlowCopy? It seems to me that there is a invalid assumption made that the caller to SlowCopy validates the range. But I guess that only applies if called from JS?

Oct 02 '24 13:10 ronag

Can someone who can reproduce check if the following fixes the issue?

I found this reproduction example interesting. Here are some other reproductions, any lower number than these work fine. Higher are crashes. v8.deserialize(v8.serialize({a: new Int32Array(1024)})) v8.deserialize(v8.serialize({b: new Int16Array(8192)})) v8.deserialize(v8.serialize({c: new Uint32Array(1024)})) v8.deserialize(v8.serialize({d: new Uint16Array(8192)}))

no bug with (Ui|I)nt8Arrays, only multibytes, from what I can tell.

@ronag The changes in SlowCopy didn't compile (from current HEAD or that first failing commit). I've never coded in here before, but I tried changing the patch to:

   args.GetReturnValue().Set(to_copy);

but it still causes a crash in the same place.

Oct 02 '24 23:10 ramidzkh

@joyeecheung any insights? I don't understand how Buffer even comes into the picture here... e.g. v8.deserialize(v8.serialize({a: new Int32Array(1024)}))

Oct 03 '24 13:10 ronag

but it still causes a crash in the same place.

@ramidzkh the same crash?

Oct 03 '24 13:10 ronag

Yes. Maybe it's because memmove is being passed the end offset and not the length?

Oct 03 '24 13:10 ramidzkh

@ronag v8.serialize({a: new Int32Array(1024)}) returns a Buffer instance

Oct 03 '24 14:10 targos

How? Buffer is not part of v8.

Oct 03 '24 17:10 ronag

Found it. copy comes from internalBinding('buffer'). https://github.com/nodejs/node/blob/b2161d3a137e5a2582c71c798e140d2ba8f7c1d4/lib/v8.js#L370-L374

this seems like enough to stop it from crashing??
