From 50054a9223aaf79985c55ef7dd090ced15581567 Mon Sep 17 00:00:00 2001 From: Jozsef Kadlecsik Date: Thu, 16 Feb 2017 20:47:30 +0100 Subject: Fix bug: sometimes valid entries in hash:* types of sets were evicted Wrong index was used and therefore when shrinking a hash bucket at deleting an entry, valid entries could be evicted as well.
