Steps to Reproduce
I don't yet have a minimal repro project, but in the meantime here's how to repro:
$ git clone https://github.com/realm/SwiftLint
$ cd SwiftLint
$ git checkout jp-swift-syntax-swift-parser-tsan
$ swift run --configuration release --sanitize thread swiftlintThe previous commit (pointing to SwiftSyntax 0.50600.1) doesn't have this race.
Tested with Xcode 14 RC1 & macOS 12.5.1 on an Apple M1 Max.
I can avoid this race by disabling all parallelism.
