Bun segfaults when building library

[mreinertssgr]

How can we reproduce the crash?

I'm creating a simple library, that unfortunately I cannot share. This is my build file and the relevant parts of package.json

import dts from 'bun-plugin-dts';

await Bun.build({
    entrypoints: ['./src/index.ts'],
    outdir: './dist',
    minify: true,
    plugins: [dts()],
});

  "types": "dist/index.d.ts",
  "type": "module",
  "main": "dist/index.js",
  "scripts": {
    "build": "bun run build.mjs",
    "prepublishOnly": "bun run build"
  },
  "devDependencies": {
    "@biomejs/biome": "1.9.1",
    "@types/bun": "^1.1.9",
    "bun-plugin-dts": "^0.2.3"
  },
  "peerDependencies": {
    "typescript": "^5.0.0"
  },
  "dependencies": {
    "@types/argon2-browser": "^1.18.4",
    "argon2-browser": "^1.18.0"
  }

Do you import any wasm files? If so, I believe #14047 will fix this crash

[shinobu-uwu]

Yes, argon2-browser communicates with the C implementation via wasm.

That's great to hear, is there any ETA for a release including this fix?

[mreinertssgr]

Using bun canary I can confirm it's been fixed, the library builds as expected

[dylan-conway]

Great

@shinobu-uwu the fix was included in the most recent release, bun v1.1.29
