QThread在MacOS上以SIGBUS信号启动崩溃

Question

我使用QThread创建PySide2（fbs-https://build-system.fman.io/）应用程序，当我单击按钮时，我的ResetWiFi线程因Process finished with exit code 138 (interrupted by signal 10: SIGBUS)崩溃

from time import sleep

from PySide2.QtCore import QThread
from fbs_runtime.application_context import ApplicationContext
from PySide2.QtWidgets import QMainWindow, QPushButton, QVBoxLayout

import sys


class TestThread(QThread):
    def __init__(self, parent=None):
        super(TestThread, self).__init__(parent)

    def run(self):
        for i in range(10):
            print('Test')

            sleep(1)


class AppContext(ApplicationContext):  # 1. Subclass ApplicationContext
    def run(self):  # 2. Implement run()
        window = QMainWindow()
        button = QPushButton()
        window.layout().addChildWidget(button)
        self.tt = TestThread()
        button.clicked.connect(self.tt.start)
        version = self.build_settings['version']
        window.setWindowTitle("MyAppTest v" + version)
        window.resize(250, 150)
        window.show()
        return self.app.exec_()  # 3. End run() with this line


if __name__ == '__main__':
    appctxt = AppContext()  # 4. Instantiate the subclass
    exit_code = appctxt.run()  # 5. Invoke run()
    sys.exit(exit_code)

我将尝试像self.tt = TestThread()那样写，但是不起作用。 在Linux上，它运作良好。仅在MacOS上有问题。
