Playing around with parameter packs I found the Swift compiler crashing when trying to compile program attached below with "swift build"
Reproduction
import Foundation
@available(macOS 14.0.0, *)
class GenericVariant<each T>
{
private var types: (repeat (each T).Type)
private var lastStored : Int?
private var tupleElements : [Any]
init()
{
// Setup types given as type parameter pack.
types = (repeat (each T).self)
let mirror: Mirror = Mirror(reflecting: types)
tupleElements = mirror.children.map({ $0.value })
}
}Stack dump
Building for debugging...
error: compile command failed due to signal 11 (use -v to see invocation)
Please submit a bug report (https://swift.org/contributing/#reporting-bugs) and include the crash backtrace.
