I'm upgrading our source base from 2.2.19 to 2.3.11. My changes from the stock
source are minimal, just some schema additions and changes to ldap_config.hin.

I'm getting the following crash when I try to launch slapd. One very strange
thing is that even when I explicitly use -f to make sure that it's only supposed
to be using slapd.conf and not back-config, it still tries to start back-config,
and that's when it dies.

As an experiment, I tried using -f and -F together to get it to migrate the data
from slapd.conf into back-config, but the same crash occurred.

output from slapd -d -1:
<lots of normal expected schema detail output omitted>
slapd startup: initiated.
backend_startup_one: starting "cn=config"
Bus error

the stack looks like this:
