(ITS#3792) slapd replica using syncrepl segfaults if master is down
Full_Name: James Downs
Version: slapd 2.2.26 cyrus-sasl 2.1.20
OS: 5.9 Generic_118558-06
URL: ftp://ftp.openldap.org/incoming/
Submission from: (NULL) (64.95.118.32)
slapd, using syncrepl and a SASL bind, segfaults if the master is down. If the
master is up, everything works properly. If the master goes down, at the next
retry, slapd segfaults, if the master is down, slapd segfaults right after
trying to connect to the server.
