we didnt "need" the bugfixes because the code was buggy. The "building block" of a offset or pointer pointing anywhere in a file is common, that can lead to cycles. Maybe the fuzzers are not good at creating such constructs out of thin air but i wouldnt use this as argument that the code isnt containing such bugs PS: the reason why fuzzers fail to find such loops is likely because its not locally convergent. A pointer closing a loop will not run more iterations as it become closer in value to closing the loop. It doesnt loop and only in maybe 1 out of 4 billion values will infinite loop and that only if all surrounding data structures also are valid enough.
