This repo collects known test cases crashing the Swift compiler. All tests cases in the crashes/, crashes-memory-corruption/ and crashes-fuzzing/ directories are known to generate a compiler crash under the current Swift compiler compiled from the master branch (if not, please report!).
Help us towards a rock solid Swift compiler by contributing any compiler crashes you may encounter.
Happy Swifting! :-)
