parser: Illegal instruction in aarch64

[Arlanthir]

I'm trying to run oxc-parser in an aarch64 machine, running on Amazon EC2 (with ubuntu).

It fails with the error:

Illegal instruction (core dumped)

The following minimal code produces the error:

package.json

{
  "name": "testoxc",
  "type": "module",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "main": "node index.js"
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "oxc-parser": "^0.69.0"
  }
}

index.js (copied from the npm package instructions):

import oxc from 'oxc-parser';

const code = 'const url: String = /* 🤨 */ import.meta.url;';

// File extension is used to determine which dialect to parse source as.
const filename = 'test.tsx';

const result = oxc.parseSync(filename, code);
// or `await oxc.parseAsync(filename, code)`

// An array of errors, if any.
console.log(result.errors);

// AST and comments.
console.log(result.program, result.comments);

// ESM information - imports, exports, `import.meta`s.
console.log(result.module);

It resolves and installs node_modules/@oxc-parser/binding-linux-arm64-gnu.

The same code works fine on my arm64 (macOS) machine (via binding-darwin-arm64).

Testing various versions, I discovered that it stopped working in version 0.60.0 (it worked with 0.58.1.

I have feeling it's when I added mimalloc in aa3dff8

This is still reproducible in 0.70.0, in case it was supposed to be fixed.

@Arlanthir can you run sudo lscpu on your instance and give us back the output information?

Hi,
this Illegal Instruction problem is happening on my system as well - Raspberry Pi 4 with aarch64 architecture. It started between 0.58.1 -> 0.60.0 of oxc-parser

My /proc/cpuinfo:
Features : fp asimd evtstrm crc32 cpuid
that is quite reduced compared to Raspberry Pi 5 where I didn't encounter the problem.

I reported a similar issue in unrs-resolver project and it was solved by disabling mimalloc - but it broke again in version >=1.7.0 there.

@Brooooooklyn do you have any more ideas?
