Environment
You can test this error building our project at its version 0.17.0 on Xcode 10.2, Swift 5.
We also isolated the problem in this playground, and check for its error log, that you can find in attachment.

Issue Description:
Starting from Swift 5, we start to hit a "Segmentation fault: 11" error on compile time. We encountered this error in our library FunctionalKit (it built perfectly for previous versions of Swift).
We found out that the problem is on the function `zip` that we defined for our `Result` type. In particular, error occur in compile-time if exists some code that use this `zip` function.
Starting from Swift 5, it seems to me that this error caused by the fact that the return type is:
`Result<Inclusive<F1,F2>,(A,B)> where Failure == Inclusive<F1,F2>, ParameterType == (A,B)`
and compiler is not able to understand that `Inclusive<F1,F2>` conforms to `Error` protocol, as requested by our `Result` type, even if we wrote
`extension Inclusive: Error where A: Error, B: Error {}`
The text was updated successfully, but these errors were encountered:
