Fire is not happy with typealiased closures in Android project

VS 2017 .NET project with this code compiles fine, but Fire .2513 Android project fails with: Internal error: System.NullReferenceException:

typealias TestCompletionAlias = (TestParam?) -> Void
func findSomething(_ aFilter: String, completion aCompletion: @escaping TestCompletionAlias)

This compiles fine:

func findSomething(_ aFilter: String, completion aCompletion: @escaping (TestParam?) -> Void)

Test project attached.
