Hello,
The bug seems to be in the new code in pcache overlay handling cache 
refreshes. When I switched configuration with only TTL/negTTL (without 
TTR)  the crashes have disappeared from both scenarios I have used:

1. One process with back-sql + pcache (crashed with segmentation failt 
when using TTR)

2. Two processes, first with back-sql, second with back-ldap + pcache, 
that communicate over unix domain socket (crashed on assertion in 
entry_clean when using TTR)

So the bug is not fixed but is located in pcache > consistency_check > 
refresh_query
