When trying to delete the olcDbIndex-Entry (to add it afterwards with additional
indexes) in olcDatabase={1}mdb,cn=config:

dn: olcDatabase={1}mdb,cn=config
changeType: modify
delete: olcDbIndex

ldapadd -x -D cn=config -w *** -f del.ldif

the slapd process gets killed with the error message:

57a08182 ch_calloc of 1 elems of 0 bytes failed
slapd: ch_malloc.c:107: ch_calloc: Assertion `0' failed.

If I try to add an additional olcDbIndex with other values, everything works
fine.
