  • SR-11475 Inconsistent compiler segfault

Issue Description:

struct Foo<T> {
    
    struct Bar {
        let value: T
    }
    
    let parse: (String) -> Bar?
    
}
extension Foo.Bar where T == String {
    
    init(_ value: T.SubSequence) {
        self.value = String(value)
    }
    
}

Given the above code the compiler will produce a Segmentation fault: 11 when trying to compile.

It's possible to workaround this issue by replacing T.SubSequence with Substring
