You have been clear on describing the behavior you are seeing.
Maybe I wasn't clear in my reply.  While the information you
provide is suggestive, I (nor likely no other OpenLDAP developer)
cannot determine the exact cause of the problem.

That cause may well be a bug in OpenLDAP Software.  But, at present,
the information provided is not conclusive.  It certainly isn't
indicative of the particular of any software bug nor indicative
of what remedies might be appropriate.

It could be most anything.  Basically, someone needs to dig further
and find some piece of information that will lead us to the
specific cause of the problem.  Once the specific cause is discovered,
a remedy can be fashioned.

As the core file is the biggest piece of information you have, I
would suggest you start by poking about with a debugger to
determine exactly why the process segfault.

>What "additional information" do you want that I didn't provide?

Detail information would which allow a developer to duplicate
the problem on their system.  (Note that duplication on their
system is very important as open source developers are generally
most interested in problems that affect them.  If the problem is
only found on your system, then you may find it hard to find
free help.)

I though it was you who asked for help...
