SIGSEGV in OpenLDAP 2.3.20 Stable

[Xavier <xavee2004@yahoo.fr>]

Hello, 

I'm having the folowing problem with OpenLDAP 2.3.20 (stable 20060227)
which acts as a replica.
the segfault occurs when my master LDAP server which is 2.0.27 sends an
ldap modify on a DN that doesn't exists. ( I know this shouldn't happen
because this means that there is a synchonisation problem )
I think it would be better to have an error instead of a segmentation
fault.

e is NULL in the call of cache_return_entry_rw()

Following is the backtrace of the crash.

I hope this will help.

Kind regards.
