When adding an olcSyncrepl attribute in my cn=config, OpenLDAP crashed.

The syslog output is:

I have no gdb trace to give for now, if you think it is required, I will try to find time to do it. But it should be easy to reproduce the issue on your side.

Please provide your exact ldapmodify request and the database config before the modify attempt, thanks.
