[Turbopack] Build: The high bits of the position 1401321 are not all 0s or 1s: 1 #82584
Description
Link to the code that reproduces this issue
https://github.com/gredice/gredice
To Reproduce
- Checkout to branch:
next-15-4-build - Install packages with
pnpm i - Try to build the project using
pnpm build --filter=garden
Current vs. Expected behavior
Expecting all apps to build, but we get error on 2 apps that use React Three Fiber. Issue is not present with < 15.4 nextjs version, even with turbo build.
Looks like it has issues with dynamic component loaded from package (not prebuilt):
- https://github.com/gredice/gredice/blob/main/packages/game/src/GameSceneDynamic.tsx
- https://github.com/gredice/gredice/blob/main/packages/game/src/GameSceneWrapper.tsx
- https://github.com/gredice/gredice/blob/main/packages/game/src/index.ts

⚠ Support for Turbopack builds is experimental. We don't recommend deploying mission-critical applications to production.
- Turbopack currently always builds production source maps for the browser. This will include project source code if deployed to production.
- It is expected that your bundle size might be different from `next build` with webpack. This will be improved as we work towards stability.
- This build is without disk caching; subsequent builds will become faster when disk caching becomes available.
- When comparing output to webpack builds, make sure to first clear the Next.js cache by deleting the `.next` directory.
