Description
The test case is attached. It consists of simple CREATE / DROP / ALTER TABLE statements, and I can't remove any more lines from it, so I presume it's about the number of created tables. I don't exclude, however, that ALTERs can be replaced by CREATE/DROP too.

The failure is also currently triggered by leveldb test suite, if it's run normally.
