RocksDB is compiled with assertions off (-DNDEBUG). If you compile with assertions on then one triggers in column_family.cc:325: is_last_reference when running the TestSnapshotMethods test in storage/engine. Bug in our test? Bug in rocksdb?

I think I may have just run into this rather randomly, at least I didn't add -DNDEBUG:

Note all the "[ERROR] Error when reading /tmp/data_1425125833457636721 dir", are those normal?

I don't recall seeing those errors, but you also have the assertion failure and the same test is failing (TestSnapshotMethods):

engine.test: db/column_family.cc:334: rocksdb::ColumnFamilyData::~ColumnFamilyData(): Assertion `is_last_reference' failed

I'll look into this more on Monday. How did rocksdb get built without NDEBUG being set?

Closed #352 via #363.
