This repo collects known test cases crashing the Swift compiler. All tests cases in the crashes/ and crashes-fuzzing/ directories are known to generate a compiler crash under Xcode 6.3 beta 2.
Help us towards a rock solid Swift compiler by contributing any compiler crashes you may encounter.
Happy Swifting! :-)
