Bun error with read streams "panic: integer cast truncated bits"

[lotrez]

What version of Bun is running?

1.1.4+fbe2fe0c3

What platform is your computer?

Microsoft Windows NT 10.0.22631.0 x64

What steps can reproduce the bug?

I am trying to read a large csv sequentially via streams and csv-parser.

Here is the code:

import { createPinoLogger } from "@bogeychan/elysia-logger";
import { transform } from "csv";
import { parse } from "csv-parse";
import fs from "fs";

const log = createPinoLogger({
  level: "info",
  transport: {
    target: "pino-pretty",
    options: {
      colorize: true,
    },
  },
});

const parser = parse({
  delimiter: "  ",
  columns: true,
});

let headers = [];

const processRecord = transform((record, callback) => {
  log.info(record["code"]);
  callback(null, record);
});

async function main() {
  log.info("Starting readDump script...");
  if (!Bun.env.DUMP_PATH) throw new Error("DUMP_PATH is not defined");
  // create read stream of csv dumpfile
  const readStream = fs.createReadStream(Bun.env.DUMP_PATH);
  await new Promise((res, err) => {
    readStream
      .pipe(parser)
      .pipe(processRecord)
      .on("end", () => res);
  });
}

main().catch((e) => {
  log.error(e, e.name);
  process.exit(1);
});

What is the expected behavior?

It should keep running and read all lines in the csv file.

What do you see instead?

It crashes after a while with high RAM usage and disk reads.

Can you run bun upgrade --canary and then report the crash using the crash reporter? That will give us a stack trace we can use.

I am having the same issue as https://github.com/oven-sh/bun/issues/10078 when running bun upgrade --canary is there any way to get the canary version via the script?

I am having the same issue as #10078 when running bun upgrade --canary is there any way to get the canary version via the script?

Please try this:

irm bun.sh/install.ps1 -OutFile $env:TEMP\install.ps1; & $env:TEMP\install.ps1 -Version "canary"
