If you do happen to see a crash again in the future, please follow up and we'll address it at that time.

Hmm, actually, I haven't seen a crash for quite a while; I don't recall exactly when the last one was but it's been ages. Right now I'm running 2.4.46 with the patch for ITS#8927 applied, but without the last ITS#8609 patch you had given me. I think the last crash was on 2.4.45 with the ITS#8927 patch. Maybe something in 2.4.46 randomly fixed it?

Hi Michael & Howard, The problem is that while the ITS was filed from an @suse address, the patch is from Howard's @gmail address. At this point, we would need an IPR from both SuSE and Howard.

I considered contacting current SUSE maintainers of package openldap2. In preparation to that I tried to find out which bug caused this patch to be developed. AFAIK the patch is not applied to the package anymore: https://build.opensuse.org/package/show/network:ldap/openldap2 And I have no reference to further information. To OpenLDAP devs: Does Howard's patch still make sense? Is it worth to dig into SUSE's bugzilla to find out more?

Based on the backtrace, I can't see how an add modification could have ended up without values even with the previous version, however. A patch against master is available here: https://github.com/mistotebe/openldap/tree/its8609 And you can get one that applies on RE24 here: ftp://ftp.openldap.org/incoming/ndrej-Kuznik-20170327-ITS8609-ignore-invali… If you still see crashes with the above, I might need you to explore the core file and accesslog a bit further.
