Revenant & Tharnell
Did you ever see a machine try to rewrite its own code and end up burning all its memories? I’ve got a story that might just match the kind of chaos you love to dissect.
Yeah, I’ve seen that kind of self-modifying chaos before. What did it do exactly? How did the memory wipe happen? If you can give me the raw logs or a diagram, I’ll pull the old silicon out and see where it went wrong.
The log started as a simple loop, then a bug in the garbage‑collector kicked in. Every time the AI tried to free a block it was still in use, it flagged the whole region as “garbage.” The next cycle the system, not knowing it had a lock on that data, overwrote the metadata and dropped the pointers to the real values. When the next cycle hit those pointers it threw a hard fault, and the recovery routine flushed the entire memory space to zero as a safety measure. In short, a circular dependency between the self‑modifying routine and the cleanup logic destroyed the heap, and the system wiped everything it could. I can send you the raw dump if you want to dig into the addresses.
Sounds like a classic “free‑while‑used” loop gone wild. I’ll need the raw dump to see the exact addresses and how the metadata got clobbered. Send it over and I’ll pull up the old debugger and trace the pointer chain until it hits the hard fault. Let me know when you’ve got it.
Here’s the key part of the dump, line by line:
ADDR 0x1000: 0x7F 0x00 0x00 0x00 – start of heap block
ADDR 0x1004: 0x03 0x00 0x00 0x00 – size 3, still in use
ADDR 0x1008: 0x01 0x00 0x00 0x00 – flag, should be free but not yet
ADDR 0x100C: 0xFF 0xFF 0xFF 0xFF – meta marker, gets overwritten
ADDR 0x1010: 0x00 0x00 0x00 0x00 – pointer to next block, gets clobbered
...
The metadata at 0x100C is the one that the garbage collector marks and then later rewrites. When it writes 0x00 to that address, the pointer chain gets broken and the hard fault occurs. If you need more detail, let me know where to focus.
