In that case, the implicit barrier acts as cancellation point. After removing the barrier after cancel, the now unmatched barrier for the explicit cancellation point has to go as well. This has probably worked before rL255992: With the calls for the explicit barrier, it was sure that all threads passed a barrier before exiting. Reported by Simon Convent and Joachim Protze!
