Issue Description:

1. clone https://github.com/krzyzanowskim/CryptoSwift/tree/3e911edb36b57de4fa37ecbb989fd3a0bc8c59b9

  1. Open CryptoSwift.xcodeproj in Xcode

  3. Build test: Product -> Test

look at 76 `Abort trap: 6` errors. See attached build log.

The problem appears to be triggered by a combination of -enable-testing, -enable-library-evolution and -O. Here is a reduced test case:

public struct ResilientWrapper { 
  public let rawValue: Int
  static let foo = ResilientWrapper(rawValue: 0)
}

Reproduces on master as well. I'll have a fix shortly.
