  • SR-1889 Compiler Segmentation Fault with Generic typealias declared in separate module

Issue Description:

My apologies for the very poor title, it was hard to phrase. I will describe the exact issue here and I will provide the example project that can be simply open and run to see the segmentation fault: 11.

Consider you have the following typealias in a file called "Typealiases.swift":

public typealias APIResponseHandler<T> = (item: T?, error: ErrorProtocol?) -> Void

And then you want to use this typealias as a parameter type in a function in a different file. Let's call it "Functions.swift", and you have the following function there:

func bar(handler: APIResponseHandler<String>) {
    
}

As soon as you try to compile your project, the compiler will crash with a segmentation fault: 11, printing a stack trace similar to this:

1.  While reading from /Users/andyibanez/Library/Developer/Xcode/DerivedData/GenericTypealiasCrash-cfblgyklzyfwrccrdsihgezhhihe/Build/Intermediates/GenericTypealiasCrash.build/Debug-iphonesimulator/GenericTypealiasCrash.build/Objects-normal/x86_64/Functions~partial.swiftmodule
2.  While deserializing 'bar' (FuncDecl #&#8203;1)

Whoever, moving the typealias to the same file as the function (in this case, moving it to Functions.swift), the project compiles fine.
