我需要迭代地获得给定图形的最小切割分区，直到子图具有低于某个给定阈值min_node的颂歌数量。这将用作CHAMELEON聚类算法的预处理步骤。为此，我使用了METIS库和R.我为METIS库中的METIS_PartGraphRecursive ()函数创建了一个简单的包装器，我用它来调用带有.C接口的R代码。调用包装器函数是可以的，然后执行分区并返回我处理的结果，并通过消除两个分区之间的边缘来检索子图。然后我通过其中一个子图进一步分区。此调用崩溃R.崩溃跟踪显示在下面的崩溃报告部分中。 （更新）Valgrind输出如下所示（正如Martin Morgan所评论的那样）。
似乎崩溃的原因是METIS库中的一些代码。
我发布了我正在使用的METIS包装器以及我如何调用这个包装器。
崩溃后，fedora显示“检测到R-core-2.15.0-1.fc16包中存在问题”的通知。操作系统使用SIGABRT或SIGSEGV杀死R，并且错误报告工具消息告诉以下内容：
Source Problem
kernel BUG: unable to handle kernel NULL pointer dereference at 00000004
我的系统：
$ uname -r
3.3.7-1.fc16.x86_64
有人可以帮我解决这个问题吗？

从以上分割一次生成的metis格式的图形，这在这个特定的例子中正常工作。但是，如果我采用其中一个分区组件并进一步重新分区，则程序崩溃。第一个分区崩溃时，使用600个点的较大数据集也是如此。
