I discovered an uninitialized variable bug in the patch I posted for
multiple databases.
In the constructor for "Display", the member variable "search_policy"
should be initialized to NULL.
search_policy = NULL;
It is actually for the "search_policies" feature, which is probably
redundant due to "allow_in_form". So, once the code for
"search_policies" is stripped away, the above problem will
be irrelevent.
