  "message": "Mitigate use-after-free due to overflow of RefcountAndFlags::count_\n\nDetects refcounts for Cord going too high, resulting in a fatal error in that case. Since the check happens after the increment, we stay conservative with the bounds and leave a good deal of margin to mitigate the chances of Unref() racing with Ref() and happening earlier than its check, which could still result in a use-after-free.\n\nPiperOrigin-RevId: 945345773\nChange-Id: Ide1151618ae836fd30dbc0a476e29ba85ca45862\n",
