Passing Parameter Pack Between Methods Crashes the Compiler #83194
Description
Description
When trying to pass a parameter pack from one method to a second with a similar definition, the compiler crashes.
Reproduction
public protocol MyProtocol: Sendable, CustomDebugStringConvertible { }
public final actor MyActor {
var condition: Bool = false
func startConditionally<each MyType: MyProtocol>(_ types: (repeat each MyType)) async throws {
guard condition else { return }
try await start(types)
}
func start<each MyType: MyProtocol>(_ types: (repeat each MyType)) async throws {
for type in repeat each types {
print(type.debugDescription)
}
}

SwiftCompile normal arm64 /Users/Khan/Desktop/Anchor/Sources/Anchor/Replication/AnchorClient.swift (in target 'Anchor' from project 'Anchor')
cd /Users/Khan/Desktop/Anchor/.swiftpm/xcode
Command SwiftCompile failed with a nonzero exit code
Command SwiftCompile failed with a nonzero exit code
Expected behavior
Doesn't crash, allows me to use the first method as a passthrough method.
Environment
Apple Swift version 6.1.2 (swift-6.1.2-RELEASE)
Target: arm64-apple-macosx15.0
Additional information
This isn't specific to actors or classes, in fact the methods can be stand-alone and the compiler will still crash.
