Worked perfectly with db-4.5.20 but as soon as mysql is used a segmentation
fault happens.

Strangely, if  the mysql database tables are unpopulated then slapd starts fine.
It's only once the test tables are populated that segmentation fault happens

mysql openldap < testdb_data.sql
mysql openldap < testdb_metadata.sql
