  • SR-1512 Assertion failure: "Already marked as a fixed binding" when implementing index(_:offsetBy:limit:)

Issue Description:

This code causes a segmentation fault:

let x: String? = nil
let y: String? = nil

let z = x.map { xx in
    y.map { _ in "" } ?? "\(xx)"
}

Manually specifying the type with `let z: String? = ...` gets rid of the segmentation fault. Replacing `(xx)` by simply `xx` also gets rid of the segmentation fault.

@rudkx, another one of these (on master):

Assertion failed: (!adjacency.FixedBinding && "Already marked as a fixed binding?"), function addFixedBinding, file /Volumes/Data/swift-public/swift/lib/Sema/ConstraintGraph.cpp, line 207.
