I'm getting a slapd segfault when the server is being terminated.

Looks like your libsasl is linked to a different libldap. The backtrace you provided shows source line numbers that have no code in git ad04676. This does not appear to be an OpenLDAP bug.

You should probably find out which SASL plugin was being unloaded when this crash occurred. Seems to be a bad SASL build, actually. Closing this ITS.
