The problem was discovered in other place. Many thanks to Dan Pascu for
the help in troubleshooting.

OK...let's wait for another one.

The "row_vals[to_domain_col]" is of db_val_t type and I was insterested in
the the "null" and "val" fields of this structure.

I have upgraded openser since and the binary and the core file no longer
match, so I cannot inspect it anymore. However the definition of the
to_domain column in the database is like this:

    to_domain VARCHAR(64) NOT NULL,

so it cannot be NULL. If this info is not enough, I'll check the next time
I get a core file (I seem to get it to crash quite regularly, like once a
day).

Hi Dan,

Can you check in the core file what is the content of
row_vals[to_domain_col] variable? I want to see if the field is returned as
NULL or not.

Regards,
bogdan
