Python多线程程序退出代码-1073741819

如何解决Python多线程程序退出代码-1073741819

我正在为omegle编写一个桌面客户端，这是我第一次处理多线程编程。我的程序（似乎是Python本身）以代码-1073741819退出。

            self.chat_state = ChatState.CLOSING

    def chat(self):
        chat = RandomChat()
        while True:
            if self.chat_state == ChatState.OPENING:
                chat.start()

                    if event == ChatEvent.CHAT_READY:
                        self.message.setText("You're now chatting with a random partner.")
                        self.chat_state = ChatState.CONNECTED
                        break
                    elif event == ChatEvent.CHAT_WAITING:
                        self.message.setText("Looking for someone you can chat with...")
            elif self.chat_state == ChatState.CONNECTED:
                while True:
                    event,argument = chat.get_event()
                    if event == ChatEvent.GOT_MESSAGE:
                        message = argument
                        self.output.append("Partner: {}".format(message))
                    elif event == ChatEvent.CHAT_ENDED:
                        self.message.setText("Partner has disconnected.")
                        self.button.setText("Start")
                        self.chat_state = ChatState.NONE
                        break
            elif self.chat_state == ChatState.QUIT:
                break

def GUI():
    app = QApplication(sys.argv)
    app.setApplicationName("oclient")
    window = MainWindow()
    window.show()
    app.exec_()




if __name__ == '__main__':
    GUI()

我怀疑由于在主线程和MainWindow.chat_state中都更改了chat_thread的值而导致错误。之所以需要多线程方法，是因为函数RandomChat.get_event直到至少有一个事件可用时才返回。

可以在这里找到omegle api：https://github.com/coal0/python-omegle我也在使用pyqt5。
