[6.0] Mutex with generic value crashes compiler: Archetype without metadata

[sliemeobn]

Description

A Mutex with a generic Value inside a generic class crashes the compiler.

Swift 6.0.2, same behavior on macOS and linux docker containers (both arm and amd64).

The weirdest part is if I comment stuff out a bit to get the file compiling, I can then comment the mutex back in and it compiles without errors. After a swift package clean the crasher returns.

Happened in the wild here:
sliemeobn/elementary@fd86c1d

Reproduction

import Synchronization

final class SendOnceBox<Value>: Sendable {
    let mutex: Mutex<Value?>

    init(_ value: sending Value) {
        mutex = Mutex(value)
    }

    func tryTake() -> sending Value? {
        mutex.withLock { value -> sending Value? in
            let result = value
            value = nil
            return result
        }
    }
}

error: compile command failed due to signal 6 (use -v to see invocation)
Metadata for archetype not bound in function.
  The metadata could be missing entirely because it needs to be passed to the function.
  Or the metadata is present and not bound in which case setScopedLocalTypeMetadata or similar must be called.
