  • SR-75 Referencing a protocol function crashes the compiler

Issue Description:

Link to stack overflow issue: https://stackoverflow.com/questions/45539925/why-does-swift-not-compile-when-referring-to-protocol-method-directly#45540040

The issue is when referring to a protocol function directly such as:

protocol Test {

func test() 

{{}}}

let testFunc = Test.test // Segmentation fault 11

The compiler does not give any feedback, please see the playground for more info.
