C++互斥锁锁定错误

我正在使用一个具有工作窃取功能的线程池，但每当程序试图锁定工作队列中的互斥对象时，我都会收到一个异常错误。

我在Windows Visual Studio 2015和Ubuntu 14.04上都尝试过该程序，但都产生了运行时异常。

我已经对工作队列本身进行了广泛的测试，无法重现错误。如果我注释掉try_steal函数，我不会遇到任何错误。最后，我用std:：recursive_mutex替换了std:：mutex，但仍然会得到同样的错误。

我认为异常发生在线程池的解构过程中，即一个线程试图读取另一个已经被破坏的线程的工作队列。但是，即使在程序结束前引入了无限循环之后，也会出现同样的异常。

我想知道是否还有其他我不想检查的东西，下面你会发现相关的代码以及VS2015和Linux调用堆栈。

谢谢你的帮助。
