          Issue ID: 10067
           Summary: back-meta doesn't like an empty modify
           Product: OpenLDAP
           Version: unspecified
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Keywords: needs_review
          Severity: normal
          Priority: ---
         Component: backends
          Assignee: bugs@openldap.org
          Reporter: ondra@mistotebe.net
  Target Milestone: ---

A modify like:

dn: <dn>
changetype: modify

sent to a back-meta DB will trigger an assert on ch_malloc(0). The code also
kind of takes liberty at equating free and ch_free, which could backfire under
some (extremely rare) circumstances.
