Segmentation fault (core dumped) error at startup on v1.46+
Version: Deno v1.46.1
I'm unable to import any of the files from my project starting with v1.46. Everything worked fine in v1.45.5.
To demonstrate, I've attached a quick screen recording below where I first attempt to start up the REPL and import a function named alias. It fails with a segfault error in v1.46.1. I then downgrade to v1.45.5 and attempt the same exact thing, and it imports it with no issues at all.

I am not able to reproduce on Linux. Can you provide backtrace from a debugger like lldb?
Of course. I'll run a backtrace on it shortly and post the results as soon as I have them

@littledivy Sorry it took so long. This isn't on my local machine (it's on a codespace instance) and I ran into a bunch of config issues trying to get lldb to work.
Here's the backtrace output from rust-lldb. I only included the real meat of the log, but if you want the entire thing just let me know. This seems to be the only relevant part though.
Thanks for your help!

@littledivy based on the backtrace line frame #19: ... _$LT$swc_ecma_transforms_proposal..decorator_2022_03, I figured it must be at least related to the SWC decorators helper. So I tried removing all traces of decorators from one particular file, and bingo, it works as it should.
[!NOTE] Upon further inspection, it appears my previous statements were incorrect, and so I both apologize and retract what I said regarding the footprint of this bug. This appears now to be something specifically caused by the right combination of conditions in my particular codebase. It is not preventing the usage of Stage 3 decorators entirely, and it should not be impeding everyday users from being able to use them in their project. Sorry for jumping to conclusions 😟
@nberlette can you share your code that uses decorators that caused this problem?
@bartlomieju I've done some further investigation and narrowed down the issue. It looks like the error is specifically triggered by the use of the @bind decorator on a getter in one of the classes. This class is used extensively across the monorepo, which initially led me to mistakenly think the problem was with all decorators. I realized this mistake last night and meant to update my previous comments, but it seems I forgot to hit submit. Sorry about that.
I've included a simplified example of the code below. However, this snippet doesn't reproduce the segfault on its own, so it's unlikely to be very helpful without additional context. This bug is proving to be particularly elusive, and giving me some difficultly in coming up with an isolated minimal reproduction. Since the repo isn't public yet, I'm reluctant to share the full source here... but I'm more than happy to send you the complete file (or even the whole module graph) through a more private channel (email or Discord?) if that works for you.
// Simplified version of the working code
class WeakStorage<K extends WeakKey, V> {
#storage = new WeakMap<WeakCollection<K, V>, WeakStorageArea<K, V>>();
// Without the @bind decorator on 'storage', this works fine
get storage(): WeakStorageArea {
return this.#storage;
}
// ...
}
// However, when I add the 'bind' decorator to the 'storage' getter (with no other changes) -> segfault
import { bind } from "jsr:@decorators/bind@^0.1.2";
class WeakStorage<K extends WeakKey, V> {
#storage = new WeakMap<WeakCollection<K, V>, WeakStorageArea>();
@bind get storage(): WeakStorageArea {
return this.#storage;
}
// ...
}
I ran into this issue as well. And in my case it was caused by... as any assertion.
I have a class with methods decorated with a memo decorator and the code refuses to run (no error or anything) if there's any assertion in the constructor. Here's a minimal reproduction:
function memo(
fn: (this: Data, id: number) => string,
_ctx: ClassMethodDecoratorContext,
) {
const cache = new Map<number, string>();
return function (this: Data, id: number): string {
const val = cache.get(id);
if (val) return val;
const str = fn.call(this, id);
cache.set(id, str);
return str;
};
}
export class Data {
constructor() {
const a = 1 as any;
}
@memo
m(id: number): string {
return "";
}
}

@dsherret maybe there is a misconfigured visitor in deno_ast? need some help :)
Same issue! (see Known [email protected])
Just one-line error message (on Ubuntu 20.04.6 LTS):
[1] 139572 segmentation fault (core dumped) deno test --allow-read --allow-net ../lib
The same issue appears also on Windows 11 WSL.
To simplify the reproduction, add a file /path_to/set.ts/src/test/segfault.ts with contents
import { Bufr } from "../lib/compiling/Bufr.ts";
new Bufr();
Then run with deno 2.0.0
deno test segfault.ts
It outputs
[1] 141274 segmentation fault (core dumped) deno test segfault.ts
The same issue appears with deno run segfault.ts.
With deno 1.45.5, there are no issues.
Not sure if this is related, but I've also been seeing occasional segfaults in the CI of deployctl. Sometimes it succeeds though.
https://github.com/denoland/deployctl/actions/runs/11402529122/job/31728939591#step:8:149
/home/runner/work/_temp/811c36e8-49ba-4291-b595-443655b47377.sh: line 4: 1970 Segmentation fault (core dumped) deno run --allow-read --allow-env --allow-net ./tools/bundle.ts ./src/utils/mod.ts > ./action/latest.deps.js
Error: Process completed with exit code 139.
I just ran into this Segmentation fault on the bind decorator as well. Strangely, I didn't have to remove all usage (it only caused a crash in certain places, but not sure what the common theme is)
I think the name of this Github issue should probably be renamed to something like Segmentation fault (core dumped) error on bind decorator so that it's clear what this issue is tracking
Also, I wonder if the SWC issue is related to https://github.com/denoland/deno/issues/24745
