Apparently both bugs had been reported previously, pre-AI, if so some important questions need to be asked about how those reports slipped through without a fix.
"Looks minor, hard to reproduce, little affected area. Throw it into backlog for 2095 release cycle."
I'm very confused about what's going on. In fact as far as I can tell those specific bugs were fixed.
https://bugs.php.net/bug.php?id=78876 marks the OOM bug as closed and fixed in 2020.
It seems the AI exploration was able to find variants of those bugs that were not fixed rather than exactly those bugs themselves?
