deleting sqlite3 row_factory causes segfault

[lunixbochs]

Crash report

What happened?

import sqlite3
db = sqlite3.connect(":memory:")
del db.row_factory
db.execute("test")

-> zsh: segmentation fault python3

In connection.c, the row_factory is compared against Py_None and incref'd, but deleting it sets it to null, resulting in Py_INCREF(NULL)

CPython versions tested on:

3.14

Operating systems tested on:

macOS

Output from running 'python -VV' on the command line:

No response

Hi @lunixbochs, thanks for the clear report!
I can work on a fix for this if nobody is already doing so.
It may also make sense to add the topic-sqlite3 and stdlib labels.

Sure! I don't think anyone is actively working on it, feel free to to correct me if I'm wrong :)
