Python GDB调试segd

Question

我正在用Python运行一个程序，并用GDB进行调试。我生成了coredump，但它基本上没有提供任何信息：

root@2380bca38221:/tmp# gdb python-dbg core.09e129943799.python.1547434680 
...

Reading symbols from python-dbg...done.

warning: core file may not match specified executable file.
[New LWP 8]
Core was generated by `python /mounts/target/scripts/run_experiment_from_doodad.py'.
Program terminated with signal SIGSEGV, Segmentation fault.
