RocksDB fail

gistfile1.txt

Was trying to duplicate this test: https://github.com/facebook/rocksdb/wiki/RocksDB-In-Memory-Workload-Performance-Benchmarks
using git rev 0365eaf12e9e896ea5902fb3bf3db5e6da275d2

but all I get is this:

open error: Corruption: While creating a new Db, wal_dir contains existing log file: : 000003.log


Note that /mnt/hyc/WAL is a fresh, empty directory at the start of the run. After db_bench exits we just see that 000003.log is a zero byte file.
