qt - 在QT5.5.1示例中，FancyBrowser(基于WebEngine)在退出时崩溃

Question

我的应用程序有问题，但在禁用所有功能几个小时后，我发现标准示例 FancyBrowser 应用程序(基于 Web 引擎)也有同样的问题。

它在 QtWebEngineCore 深处的某个地方造成了一些断点(不幸的是，在 5.5.1 中，他们忘记放置符号 QtWebEngineCored.dll.pdb)。然后应用程序就退出了。

此外，在出现此异常后，会出现一些 debug.log 文件:

  [1121 / 22 1113:FATAL : resource_scheduler.cc(784)] Check failed : client_map_.empty().

它仅出现在 5.5.1 中(5.4.x 从未见过)。只是好奇，我能用它做点什么吗？

可能是调试端口的原因，你可以去掉调试端口参数试试
