• [$] Using LLMs to find Python C-extension bugs

    From LWN.net@86:200/23 to All on Wed Apr 22 06:40:09 2026
    The open-source world is currently awash in
    reports of LLM-discovered bugs and vulnerabilities, which makes for a lot more work for maintainers, but many of the current crop are being reported responsibly with an eye toward minimizing that impact. A recent report
    on an effort to systematically find bugs in Python extensions
    written in C has followed that approach. Hobbyist Daniel Diniz used Claude Code to find more than 500 bugs of various sorts across nearly a million
    lines of code in 44 extensions; he has been working with maintainers to get fixes upstream and his methodology serves as a great example of how to keep
    the human in the loop-and the maintainers out of burnout-when employing LLMs.
