Previous versions of OpenLDAP could show a sig11 when doing slapcat (using bdb backend).

The version 2.4.15 improved in this respect already though doing a slapcat with an emtpy db still results in a segmentation fault.

The following small patch by andreas.mack at erfrakon.de resolves this issue

The patch is used by the Kolab Project in productive installations

What exactly do you mean by an empty db? I see:

Please provide steps to reproduce the segfault, thanks.
