Reproduction Example/SDK Setup

https://github.com/SolarLabyrinth/sentry-bun-bytecode-repro

main.ts

import * as Sentry from "@sentry/bun";

Sentry.init({
 dsn: "https://example@example.com/1",
 tracesSampleRate: 0,
});

console.log("Success!");

Steps to Reproduce

Steps to Reproduce Failure:
Fails with v10.54.0 and v10.55.0

bun i @sentry/bun@10.55.0
bun build main.ts --compile --format=esm --bytecode --outfile main
./main

This build fine with previous versions:

bun i @sentry/bun@10.53.1
bun build main.ts --compile --format=esm --bytecode --outfile main
./main

This also builds fine without --bytecode:

bun i @sentry/bun@10.55.0
bun build main.ts --compile --format=esm --outfile main
./main

Expected Result

Success!
