gdb 版本 >7 的 对python调试有特别支持,参考:

https://docs.python.org/devguide/gdb.html?highlight=gdb

https://blog.****.net/BaishanCloud/article/details/76422782

可用命令有:

py-bt
py-list
...

示例:

centos7, default python2.7, 自自安装 python3.5,需要在gdb中加载3.5的 libpython.py,本机路径为 /home/cl/python/Python-3.5.3/Tools/gdb

(gdb) python
>import sys
>sys.path.insert(0, "/home/cl/python/Python-3.5.3/Tools/gdb")
>import libpython
>
end
(gdb) py-bt
...

Notes:

gdb中运行发生死锁、阻塞等情况,导致无法暂停的,可以在外部运行,然后 gdb attach pid
