调用Python C-extension模块时出现分段错误

我有一个C扩展模块，我正在使用CentOS构建和使用 distutils。

python setup.py build_ext --inplace

然而，当我尝试在64位Ubuntu机器中使用相同的（当然再次重新编译以生成.so文件）时，我在调用c模块时遇到了分段错误。

我正在使用Python 2.7。

使用gdb运行它我得到以下跟踪

[Switching to Thread 0x7ffff232f700 (LWP 4685)]
convertsimple (freelist=0x7ffff232c840, bufsize=256, msgbuf=0x7ffff232c8d0 "", flags=0, 
p_va=0x54a812, p_format=<synthetic pointer>, arg=0x808430) at Python/getargs.c:716
716 Python/getargs.c: No such file or directory.

注意当我编译扩展模块并在那里使用它时，相同的代码在CentOS 64位中工作正常。
