In order to trigger the bug what's needed is to call ZINTERSTORE resulting into an empty set created, bug against a key that already existed. The command was not propagated, so the replica ended with the key that the master removed. Sequence of command to reproduce: redis-cli hset 446 34 905 redis-cli hset 446 393 911 redis-cli zadd 966 0.085412045980529885 652 redis-cli zadd 645 0.25081839284432045 280 redis-cli zinterstore 446 2 966 645
Check the 'doc' directory. doc/README.html is a good starting point :)
