SWIG&C/C++Python API已连接-SEGFAULT

我的任务是创建双程序。开始时，我启动了一个C程序，通过Python的C/C++API调用一些Python方法。调用之后调用的方法是使用SWIG创建的函数。我给你们看我的样本，在我被给出分段错误后，我还从gdb返回跟踪

主要条款c：

最后一个想法是我的Makefile&SWIG配置文件

生成文件：

rm-rf*.o

程序由./main调用，并有以下输出：

计数器究竟是在哪里定义的？计数器是在utils.h中定义的静态变量。但我认为删除变量与我的问题无关。计数器到底是在哪里定义的？计数器是在utils.h中定义的静态变量。但我认为删除变量与我的问题无关。
