Intermittent Segmentation Fault when Running TypeScript Script with Bun

[masaru-1998]

How can we reproduce the crash?

1. Create a TypeScript project with a script that generates OpenAPI schema.
2. Set up a package.json with a script to run the TypeScript file: "scripts": { "generate:schema": "bun run ./scripts/api/generate-open-api.ts" }
3. Run the command bun run generate:schema multiple times.
4. Observe that sometimes the script executes successfully, while other times it crashes with a Segmentation Fault.

Note: The crash seems to occur randomly and is not consistently reproducible, which makes it challenging to debug.
