Summary: A recent commit make periodic compaction option valid in FIFO, which means TTL. But we fail to disable it in crash test, causing assert failure. Fix it by having it disabled. Pull Request resolved: https://github.com/facebook/rocksdb/pull/5993 Test Plan: Restart "make crash_test" many times and make sure --periodic_compaction_seconds=0 is always the case when --compaction_style=2 Differential Revision: D18263223 fbshipit-source-id: c91a802017d83ae89ac43827d1b0012861933814
