Thank you. I am quite puzzled by this failure. There was an similar failure when /proc/[pid]/setgroups was read (if I recall correctly). I don't see how that change could result at failures during open or failures during boot. I added a new file to proc which any reasonable system should leave alone. Are you by chance running trinity during boot? If the reproducer gave me any clue about which file that was opened or which code path this happened on I would be bery interested. If for no other reason that to confirm that I have fixed the issue. I have rewritten the implementation of /proc/[pid]/setgroups so it is simpler and more robust and does not have any errors I can detect. Thank you very much for picking up my for-testing branch and beating up on it.
