yep:  for example,

      if (PQresultStatus(*res*) != PGRES_TUPLES_OK)
        {
                LOG_ERROR("SELECT failed: %s", PQerrorMessage(conn));
                LOG_DEBUG("ROLLBACK TRANSACTION AND CHAIN");
                *res* = PQexec(conn,"ROLLBACK TRANSACTION AND CHAIN");
                LOG_ERROR("INVALID_FILE_ADDRESS %08X",fa);
                rc = ERR_INVALID_FILE_ADDRESS;


See highlighted bits.  You're reusing the res object before clearing
it.  there may be other cases, but this jumped off the page.
