swift - 中止陷阱 : 6 in protocol extension with typealias definitions

Question

我有以下代码在 Xcode 9.2 标准构建系统和 swift build -c release 中编译和运行，但它不编译并给出 abort trap: 6 when使用 New Build System (Preview) 或 swift build

构建项目

import Foundation

protocol RestProtocol {
    associatedtype PostModelType: Codable
    associatedtype GetModelType: Codable
    associatedtype PostResponseType: Codable
}

extension RestProtocol {
    static func consume(with: [String: Any],
                        completion: @escaping (GetModelType?, Error?) -> Void) {
        completion(nil, nil)
    }

    static func produce(with: PostModelType,
                        completion: @escaping (PostResponseType?, Error?) -> Void) {
        completion(nil, nil)
    }
}

struct Model<T: Codable>: Codable {
    var code: Int?
    var message: String?
    var success: Bool?
    var result: T?
}

struct Service: RestProtocol {
    typealias PostModelType = DetailsModel
    typealias GetModelType = Model<DetailsModel>
    typealias PostResponseType = Model<DetailsModel>
}

struct DetailsModel: Codable {
    var response: String?
}

Service.consume(with: ["Key": "value"]) { (response, error) in
    print("This compiles in Xcode and swift build -c release but gives Abort trap: 6 in swift build")
}

提前感谢您的帮助。

显然，这是构建系统中的一个问题，在 Xcode 中混淆了区分大小写的文件命名。在同一个模块中包含 Account.swift 和 account.swift 等文件会导致错误。
