If I do that the problem goes away until the next bulk update! An interesting
fact is that add operations seem to be safe -- I do ___large___ add operations
which never corrupt the indices but it's enough to add objectClass=posixAccount
to ~20 entries to loose this AV-pair on half of them in the objectClass index!

I am about to try this. I have built a version with gdbm and a version with

version changes I reload the db from ldif to elliminate file format problems.
Will get back to you (probably tomorrow) when I have written some test-
