olcDbConfig not correctly populating DB_CONFIG file

[Dusty Doris <openldap@mail.doris.cc>]

openldap 2.3.4
freebsd 5.4
db 4.3.28

I have just started testing with parts of the new ldif configuration in
slapd.d and have found (in my experience) that the olcDbConfig settings
aren't correctly populated into the DB_CONFIG file upon restart.

I start from scratch and create a DB_CONFIG file with the following:
set_cachesize 0 536870912 1
set_lg_regionmax 1048576
set_lg_bsize 2097152
set_lg_max 10485760
set_flags DB_LOG_AUTOREMOVE
#only for database loading/reindexing w/ slapadd
#set_flags DB_TXN_NOSYNC
#set_flags DB_TXN_NOT_DURABLE

Then I start slapd and the slapd.d directory is populated.  I open
cn=config/olcDatabase={1}hdb.ldif and view it.  It shows the following.

olcDbConfig: {0}set_cachesize 0 536870912 1
olcDbConfig: {1}set_lg_regionmax 1048576
olcDbConfig: {2}set_lg_bsize 2097152
olcDbConfig: {3}set_lg_max 10485760
olcDbConfig: {4}set_flags DB_LOG_AUTOREMOVE
olcDbConfig: {5}#only for database loading/reindexing w/ slapadd
olcDbConfig: {6}#set_flags DB_TXN_NOSYNC
olcDbConfig: {7}#set_flags DB_TXN_NOT_DURABLE

If I then shutdown slapd, delete the DB_CONFIG file from
/var/db/openldap-data and restart slapd.  The DB_CONFIG file is recreated,
but the first entry of each line is ommitted.

So the file ends up looking like this:

0 536870912 1
1048576
2097152
10485760
DB_LOG_AUTOREMOVE
for database loading/reindexing w/ slapadd
DB_TXN_NOSYNC
DB_TXN_NOT_DURABLE

Debug shows this.  It does core, but I believe that is due to the
DB_CONFIG file being incorrect, so I don't think it will show anything
relevent.  Let me know if you want me to run gdb info on it.
