 Description   

I try to use lgpl version of mysql c connector. When I link test program using:
mariadb_config --libs and mariadb_config --cflags, then I got memory leak.
When I link the same program using mysql_config --libs and mysql_config --cflags,
then there is no memory leak.
Is it a library bug or there is a bug in my test program?
My test function:

   for(;;) {
 
                MYSQL mysql;
 
                int arg;
 
                mysql_init(&mysql);
 
                mysql_options(&mysql, MYSQL_READ_DEFAULT_GROUP, "client");
 
                mysql_options(&mysql, MYSQL_OPT_COMPRESS, 0);
 
                mysql_options(&mysql, MYSQL_OPT_NAMED_PIPE, 0);
 
                arg = MYSQL_PROTOCOL_SOCKET;
 
                mysql_options(&mysql, MYSQL_OPT_PROTOCOL, &arg);
 
                if(!mysql_real_connect(&mysql, "localhost", DBUSER, DBPASS, DBNAME,
 
0, 0, 0))  {
 
                        fprintf(stderr, "Failed to connect to database: Error: %s\n", mysql_error(&mysql));
 
                        return 1;
 
                }
 
                mysql_close(&mysql);
 
        }
 
        return 0;

I monitor memory usage with:

while true; do ps -o rss $PID; sleep 1; done

Without mysql_real_connect() there is no memory leak.
