If we hit a segfault from within python, we just get
"Segmentation fault (core dumped)"
Comment 1 Douglas Bagnall 2020-02-06 11:02:28 UTC
Things are a bit better with Python 3.7 and above. 

You can use

  python3 -X faulthandler
  python3 -X dev

to see the *python* stack at SEGV time.

(see https://docs.python.org/3.7/using/cmdline.html#id5)

The '-X dev' devmode is better described in 


That's the 3.9 docs, but it is mostly the same with 3.7 as far as I can tell.
