    Description

      Calling either QThread.wait() or QWaitCondition.wait() causes an access violation/segfault and hard freezes python.

       

      class Producer(QtCore.QThread):
    def run(self):
        time.sleep(2)


if __name__ == "__main__":
    app = QtCore.QCoreApplication(sys.argv)
    producer = Producer()
    producer.start()
    print("About to call Qthread.wait()")
    producer.wait() # crashes
    print("Qthread finished")

       

      Tested on Windows 7/10 with Pyside2 5.15.0

      Works as expected on 5.14.1.

       

      Possibly (probably) related to PYSIDE-1282
