C++ QProgressDialog:：setValue产生随机堆栈溢出

我正在开发一个无法共享源代码的大项目。在该项目中，我们在windows（而不是ubuntu）中遇到了一些重复性较差的堆栈溢出错误，调试器的堆栈跟踪显示，设置为窗口模式的进度对话框正在递归调用QProgressDialog:：setValue（int）

我创建了这个小的QProgressDialog，试图重现错误。虽然我在使用这个示例时没有遇到堆栈溢出错误（在Windows或Ubuntu中都没有），但当我通过在调试器中添加断点来查看QProgressDailog:：setValue时，我发现它也会递归地调用自身（在两个操作系统中），只是没有足够的时间产生堆栈溢出。最令人印象深刻的是，有时它只调用QPrigressDialog:：setValue一次

请参见调用堆栈或窗口的示例：
