/Users/buildnode/jenkins/workspace/swift-master-source-compat-suite-debug/swift-source-compat-suite/project_cache/ReactiveCocoa/Carthage/Checkouts/ReactiveSwift/Sources/Property.swift:50:10: error: the compiler is unable to type-check this expression in reasonable time; try breaking up the expression into distinct sub-expressions
                return BindingTarget(lifetime: lifetime) { [weak self] in self?.value = $0 }
                       ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

All of my changes are related to “diagnostic mode” so they shouldn’t affect performance. Could AutoDiff changes have caused this problem?

I’m testing revert of my changes - https://github.com/apple/swift/pull/30649
