Swift命令行工具以调试模式构建，但未发布

Question

我正在尝试构建此命令行工具： https : //github.com/kindlychung/swiftsci

在调试模式下，它可以正常编译，并且二进制文件可以按预期工作。 但是当我在发布模式下构建时，出现以下错误：

关于发生了什么的任何想法？

从最后一行来看，似乎我在这里做错了 ：

let funcMap = [
        "sci": {
            (s: String) throws -> String in try s.sci()
        },
        "ibook": {
            (s: String) throws -> String in try s.ibook()
        }
]

我不确定为什么这样做不行，但是我尝试了一下：

func fSci(s: String) throws -> String {
    return try s.sci()
}
func fIbook(s: String) throws -> String {
    return try s.ibook()
}

let funcMap = [ "sci": fSci, "ibook": fIbook ]

而且我仍然遇到相同的错误。 奇怪。

Answer 1

由于分段错误，编译器崩溃。 这意味着在这种情况下，编译器已损坏。 您应该通过swift.org错误跟踪程序将错误报告给Apple。 确切地说，这不是Swift问题，而是工具链中的错误。

错误消息表明问题是由于某个地方的关闭而引起的，但他们没有说明是哪一个。 错误消息中实际上没有任何内容指向您正在查看的闭包，而不是其他闭包（如果您查看最后一行，则会看到项目中的每个Swift文件都已列出）。 闭包在语法上是有效的（否则，编译器会更早地抱怨而不是崩溃），但是有关它的事情正在使编译器严重脱离轨道。

我不特别喜欢的一种解决方法是，通过选择单文件优化来禁用整个模块优化：
