Hi Sven,

To start with, you're filing this ticket with the wrong group.  You would 
want to file this with http://www.openldap.org/its/

I think what you are reporting has already been reported to OpenLDAP as 
<http://www.openldap.org/its/index.cgi/?findid=7113>

I would ask that you try the current RE24 checkout from GIT and see if you 
still encounter the issue.  If so, then please file an ITS in the OpenLDAP 
tracker with the backtrace, etc, information.  If you need to arrange that 
to be provided privately, that can be worked out with the OpenLDAP 
developers.
