我试图调试一个segfault，我在一个多线程的qt webkit应用程序中获取。我安装了Python-DBG为了让我在gdb漂亮印花的目的，并获得启动python-dbg在调试时找不到Py_InitModule4
python2.7-dbg node.py

Original exception was:

我得到同样的事情，当我运行一个版本不msgpack使用脚本以下错误.. 。

在这两种情况下它看起来Py_InitModule4 ...任何想法的Python专家？代码运行良好（除了segfault以后）与普通python 2.7
如果有一个更容易的方式来在gdb中获得漂亮的打印我也打开。基本上只是寻找一个python风格stacktrace
