Dear all,
  I found a bug and don’t know where to file it. Just send the mail to let you 
know.
In the apr_dbd_freetds.c +630, function freetds_open:

sql = apr_palloc (pool, sizeof (apr_dbd_t));  // should be  apr_pcalloc, like 
apr_dbd_pgsql_open.c +1231

if calls dbd_freetds_query after freetds_open,  it will fail.
static int dbd_freetds_query(apr_dbd_t *sql, int *nrows, const char *query)
{
    if (sql->trans && sql->trans->errnum) {
        return sql->trans->errnum;
}
…

Please confirm this issue.
