Bun.plugin segfault

[huseeiin]

How can we reproduce the crash?

plugin.ts

import { writeFileSync } from "fs";
import { dirname, resolve } from "path";

Bun.plugin({
  name: "toml",
  setup(build) {
    build.onResolve({ filter: /\.toml$/ }, (args) => {
      const path = resolve(dirname(args.importer), args.path);
      writeFileSync(
        `${path}.d.ts`,
        `export default ${JSON.stringify(require(path))}`
      );
      return { path };
    });
  },
});

then register it as a plugin with bunfig.toml:

preload = "./plugin.ts"

and run this code:

test.ts

import bunfig from "./bunfig.toml";
console.log(bunfig);

Relevant log output

i sometimes also got this:

1 | import bunfig from "./bunfig.toml";
2 | console.log(bunfig);
    ^
SyntaxError: Unexpected token ')'
      at <parse> (/home/hussein/project/test.ts:2:1)
