Body

I have a problem where my code is crashing the swift-frontend in GitHub Actions.

Locally, this same code has no problems. It builds and tests without warnings or errors with Xcode 15.4 (same Xcode that is in GitHub Actions image).

An Apple engineer encouraged me to file a Swift bug about this, which I did, where you can see all the details and further info: swiftlang/swift#75830

Has anyone seen anything like this? Any advice or workarounds? Fixing Swift bugs is cool, but I’d just like my code to compile, and the action to pass. 🙃
