child_process.spawnSync() failure when readline module is also used

[dhbaird]

What version of Bun is running?

1.1.13

What platform is your computer?

Linux

What steps can reproduce the bug?

echo | bun fail.mjs

of the following:

// fail.mjs
import readline from "node:readline";
import child_process from "node:child_process";
import { stdin } from 'node:process';

const reader = readline.createInterface({ input: stdin });
reader.question("", () => {
    const { stdout } = child_process.spawnSync("bash", ["-c", "echo hello"], {
        input: new Uint8Array(0),  // works if Uint8Array(1)
        stdio: ["pipe", "pipe", "inherit"]
    });
    console.log(stdout);  // expect: Buffer(6) [ 104, 101, 108, 108, 111, 10 ]
});

What is the expected behavior?

Buffer(6) [ 104, 101, 108, 108, 111, 10 ]

What do you see instead?

bash: line 0: echo: write error: Bad file descriptor
Buffer(0) [ ]

Additional information

Works if input of spawnSync is Uint8Array(1).
Works if input of spawnSync is "" (empty string).
Works if reader.question() is removed.
Works with node.js.

does this still reproduce for you? I'm not seeing this on Bun 1.1.27 (you may need to run bun upgrade)

I can reproduce on Bun 1.1.43 (Linux).
