While investigating ITS#3817 I found a number of:

Assertion failed: info->al_slot > 0, file alock.c, line 207

I've finally narrowed that down to a reasonable reproduction case. At a glance,
it appears to occur with slapo-glue and disparate suffixes, that is dc=a and
dc=b but not dc=x,dc=a and dc=y,dc=a.

To play along at home:

1. ./run -b hdb test011 should succeed.

2. Edit the slapd.1.conf; we'll move "Groups" to be far away. For instance:

49c49
< suffix                "dc=breakme,dc=org"
---
> suffix                "ou=Groups,dc=example,dc=com"
51c51
< rootdn                "cn=Manager, dc=breakme,dc=org"
---
> rootdn                "cn=Manager, dc=example,dc=com"
76c76
< #glue-sub             "ou=Groups,dc=example,dc=com"
---
> glue-sub              "ou=Groups,dc=example,dc=com"

3. Clean up the databases thoroughly:
rm testrun/db*/*

4. slapadd again:
slapadd -b "dc=example,dc=com" -l testrun/ldif.flt -f testrun/slapd.1.conf


On my system, this returns:

Assertion failed: info->al_slot > 0, file alock.c, line 207
Abort


Since example.com is hosted as a hdb, I'd expect that slapadd to work.
