Summary: Not sure where or how it happens, but using a recent CircleCI failure I got a reliable db_stress reproducer. Using std::unique_ptr appropriately for managing them has apparently (and unsurprisingly) fixed the problem without needing to know exactly where the problem was. Suggested follow-up: * Three or even four levels of pointers is very confusing to work with. Surely this part can be cleaned up to be simpler. Pull Request resolved: https://github.com/facebook/rocksdb/pull/12805 Test Plan: Reproducer passes, plus ASAN test and crash test runs. I don't think it's worth the extra work to track down the details and create a careful unit test. ``` ./db_stress --WAL_size_limit_MB=1 --WAL_ttl_seconds=60 --acquire_snapshot_one_in=10000
