Hi Mark, That's unfortunate. Assuming you're on macOS, do you mind running
ls ~/Library/Logs/DiagnosticReports/swift*.crash that might reveal some compiler crash reports. If yes I think the best would be to file a bug for these crashes on http://bugs.swift.org . What presumably would be most helpful is a small reproduction of that crash but I realise that can be hard at times...
