XC8: Segmentation fault 11 while archiving

Hey,

I'm having troubles archiving my App using WeakArray (https://github.com/zaubara/WeakArray) that's included in a different framework. It looks a little like this:

App

Crashlytics etc.

Library (framework)

MyPrivateFramework

WeakArray

SwiftyJSON

PromiseKit

PureLayout

LotsOfOthers

I'd like to use WeakArray in Library and the App as well, and however I include the framework, the app builds and runs fine; archiving however throws this seg fault:

1. While running pass #4733 SILModuleTransform "Mandatory Inlining".
2. While deserializing decl #900 (XREF)
3. Cross-reference to module 'WeakArray'
  ... WeakArray
  ... items

I updated the framework only crudely to Swift 3, but it seems to run fine. The likely offending code:

public struct WeakArray<T: AnyObject>: Sequence, CustomDebugStringConvertible, ExpressibleByArrayLiteral {
  // MARK: Private
  fileprivate typealias WeakObject = Weak<T>
  fileprivate var items = [WeakObject]()

I can use WeakArray in MyPrivateFramework just fine, however reusing it in the Library or the App - no matter how I try and link or embed it again - doesn't seem to work. I had no issues in XC7.

Maybe some compiler bug relating to generics? Thanks!
