Compiler crash with trailing closure involving variadic types

[xAlien95]

Description
The following code is causing a compiler crash, with the error message Assertion failed: (origPackType.matchesPack(substPackType)), function PackElementGenerator, file AbstractionPattern.cpp, line 804 (Full output/stack dump).

if #available(macOS 14.0.0, *) {
  struct Tuple<each Element> {
    let element: (repeat each Element)

    init(_ element: repeat each Element) {
      self.element = (repeat each element)
    }
  }

  struct Wrapper<each Element> {
    let content: Tuple<repeat each Element>

    init(_ content: () -> Tuple<repeat each Element>) {
      self.content = content()
    }
  }

  _ = Wrapper { Tuple(1, 2) }
}

Steps to reproduce
Build the script with the latest Swift development snapshot.

Expected behavior
The compiler shouldn't crash.

Environment

• Swift compiler version info: swift-DEVELOPMENT-SNAPSHOT-2023-08-03-a.xctoolchain, Apple Swift version 5.9-dev (LLVM 880cf58f10f5f0a, Swift f62c6c062e55591)
• Xcode version info: Xcode 14.2, Build version 14C18
• Deployment target: macOS 12.6.8 (21G725)

Additional context
The script compiles if you use an intermediate closure variable:

let closure = { Tuple(1, 2) }
_ = Wrapper(closure)
