Issue Description:

Compiling using the nightly-main-focal docker image fails. My code uses the withThrowingTaskGroup concurrency Task API. Please see the GitHub Repo and the GitHub Actions Run for a basic example. I do not get this compiler crash when building with Xcode 13 Beta 5 on macOS 12 Beta 7

Thanks, we'll have a look – so it seems this only fails on Linux right?
