c - python tracing a segmentation fault

Question

I'm developing C extensions from python and I obtain some segfaults (inevitable during the development...).

I'm searching for a way to display at which line of code the segfault happens (an idea is like tracing every single line of code), how can I do that?

Answer 1

If you are on linux, run python under gdb

gdb python
(gdb) run /path/to/script.py
## wait for segfault ##
(gdb) backtrace
## stack trace of the c code
