[Issue 10067] New: back-meta doesn't like an empty modify

https://bugs.openldap.org/show_bug.cgi?id=10067

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.
