Why is my python script crashing?

Question

Python

Greetings,
I would like to clarify right away that I am not waiting for one miracle answer that will immediately help solve this problem (but it would be great), I am more interested in the sequence of actions for debugging such errors, I will try to provide all the output of logs / screenshots, etc. promptly.

There is a script (parser) in which all the code is covered with Exceptions (I did this in the hope that I would understand at what stage of work the error occurs) which uses the DBMS to save the result of its work, and which constantly crashes stably while throwing various errors (so far I have only met these three):

1 error:
Segmentation fault

2 error:
malloc(): corrupted top size

3 error:
free(): corrupted unsorted chunks

Python version:

Python 3.9.2

DBMS:

mysql Ver 15.1 Distrib 10.5.11-MariaDB, for debian-linux-gnu (x86_64) using EditLine wrapper

What first came to mind to see (alas empty):

ls -la /var/log/mysql/
total 0
drwxr-s--- 1 mysql adm     0 Sep 27 08:35 .
drwxr-xr-x 1 root  root 2114 Nov 14 04:16 ..

dmesg | grep -i error

As far as I managed (this is just an assumption) to understand, the error crashes due to incorrect memory addressing when working with the following libraries:

libc-2.31.so
_dlib_pybind11.cpython-39-x86_64-linux-gnu.so

Judging by the name of the so file, you seem to be using a package ( dlib ) to access the database. Try asking there. Or switch to the "official" connector .
