Issue Description:

When running tests for PathKit at this commit kylef/PathKit@4151a7e on Linux, the compiler crashes with this error:

# swift test

Just to check, this same commit builds fine with Swift 4.2?

Yes it does with `Swift version 4.2.1 (swift-4.2.1-RELEASE)`

Also note this fails with tools-version 4.2 and 5.0 with the 5.0 release
