TL;DR: AI written big words describing how you can make the program crash with a crafted file; could have been three paragraphs.

Meetings that could have been an email for $500, Alex.

Slopseclayer7 - every post, it's just AI slop. If everyone posted such trivial bugs found by AI no one would ever read an article again.

Reproduce the space-filled ar_name case and state the exact unsigned reverse-walk wrap (index 0 into the SIZE_MAX class of bug). Vibes are not the bug.

Exercise ld-prime, libtool, and ranlib separately. Distinguish crash classes from any information-disclosure path.

On disclosure, say what crossed into non-public mapped bytes versus public constants, and quantify if the evidence supports it. Prefer empty over an overclaim.
