is duplicated by:

  • SR-5200 IRGen Verification failure with classes inheriting from a Codable base class
  • SR-5170 Complex expression with coding - broken function found

Issue Description:

The Swift 4 compiler

Apple Swift version 4.0-dev (LLVM 7d1af4e028, Clang 14f7ac7518, Swift 52fcadf409)
Target: x86_64-apple-macosx10.9

crashes for this program

public class Base {
    public init(foo: Int) {
    }

    public class func giveFoo() throws -> Int {
        return 8
    }
}

public class Sub: Base {
    public init() throws {
        try super.init(foo: Base.giveFoo())
    }
}

Remove the throws and the try and it's happy. Swift 3 is just happy 🙂
