To reproduce, it's enough to start server with valgrind, e.g.
/usr/bin/valgrind.bin --suppressions=/data/bzr/mysql-5.6-leveldb/mysql-test/valgrind.supp --tool=memcheck --leak-check=yes --show-reachable=yes mysqld ...
then run
create table t1 (pk int primary key) engine=LevelDB;
and shut down the server.
MTR test case:
CREATE TABLE t1 (pk INT PRIMARY KEY) ENGINE=LevelDB; DROP TABLE t1;
