A bug (ITS#4801) was recently fixed in slapo-dynlist(5) which appeared 
in conjunction with slapo-valsort(5).  The fix is available both in HEAD 
and in re23 CVS (tag OPENLDAP_REL_ENG_2_3).  The relevant change is in 
servers/slapd/overlays/dynlist.c 1.28 -> 1.29 (HEAD) or 1.5.2.9 -> 
1.5.2.10 (re23).  Could you please check if it does any good to the 
issue you reported?

Thanks, p.
