Python PyEnchant分割错误或无效指针

我有一个调用PyEnchant的多线程Python应用程序。我不是Python专家，大部分代码都来自第三方。我所做的是添加代码以从多线程应用程序中调用PyEnchant。由于我进行了更改，因此应用程序运行的时间长短不一，然后崩溃。我在Ubuntu 12.04上运行它。我得到的错误，像这样的：Python PyEnchant分割错误或无效指针

阅读另一篇文章我试过的ulimit但

ulimit -s unlimited

和各种其他值做了n似乎没有帮助。

我已经监视了运行“top”的应用程序，它似乎没有使用太多的资源。有时它会在15分钟内运行15分钟。在这些运行过程中，它处理数百个字符串并发现数百个未知单词。代码运行的机器没有已知的问题，它是我的开发机器其他一切运行稳定。

任何人都可以阐明这些错误是什么意思？有什么我应该或不应该在我的Python代码中进行排序吗？我想这是一个内存问题（我知道的东西很少），我应该检查内存泄漏等？

我做了一些更多的测试，发现它对单个工作线程工作正常。在Googleing之后，我发现http://aspell.net/在“需要完成的事情”中说过; “让Aspell线程安全，尽管Aspell本身并不是多线程的，但我希望它是线程安全的，以便它可以被多线程程序使用。”我通过附魔与PyEnchant一起使用Aspell，所以我猜想我所看到的是可以预期的。我接触了附魔http://www.abisource.com/projects/enchant/的作者，他们说：“附魔本身就是线程安全的，不幸的是，它的一些后端可能不是，比如你在Aspell中找到的，这是我们可以在Enchant中解决的事情，通过序列化对Aspell字典的所有访问，从而隐藏线程不安全性给用户。“并可以提交增强请求。所以我提出了一个改进请求，并期待在适当的时候进行改进。
