None of the changes in that window seem super obviously fraught or risky he= re, skimming them. Half wondering if 21fce617d1de231a30833cdd9819ef61277b08d8=20 built with LLVM 17 would break the same way and it's some weird optimization going awry, but I haven't remotely tried testing this enough to say that. Anything you can tell us about the datasets on the pool? I'm going to go try reproing this in a 15 VM, but if it doesn't trivially reproduce for me (tho= ugh if syzkaller is hitting it, maybe it will), then knowing things about the s= etup hitting it would be useful. --=20 You are receiving this mail because: You are the assignee for the bug.=
