What happened?

When running a dev build via bun expo run:ios, the app crashes with an infinite recursion in Uniwind’s Metro resolver. The error is a NativeModules stack overflow. This does not happen in Expo Go (same repo, same code).

Error signature:

[runtime not ready]: RangeError: Maximum call stack size exceeded (native stack depth)
get NativeModules
get NativeModules
...

Findings / root cause hypothesis:

• Uniwind rewrites require(\"react-native\") → uniwind/components for most modules.
• Inside uniwind/components, many getters call require(\"react-native\") again (to access NativeModules, etc).
• If Uniwind fails to detect that the origin is inside Uniwind, it rewrites again → infinite loop.
• Guard currently uses:
  context.originModulePath.startsWith(cachedInternalBasePath)
• Under Bun, the path looks like:
  .../node_modules/.bun/uniwind@1.2.7/node_modules/uniwind/dist/module/components/...
  but cachedInternalBasePath is:
  .../node_modules/uniwind/dist/module
• That mismatch makes isInternal false → rewrite loop.

Suggested fix:

• Normalize paths with realpathSync (or equivalent) for both cachedInternalBasePath and originModulePath, or
• Use a package-boundary check (e.g. /node_modules/uniwind/) instead of a raw startsWith on a non-normalized path.

Steps to Reproduce

1. Clone the repo below
2. bun install
3. bun expo run:ios
4. Launch the dev build (crash occurs on startup)

Note: Expo Go does not crash.
