Mysql_free_result() is causing mysql to close.
Every time I call mysql_free_result() mysql.exe terminates unexpectedly. Here is what I am doing:

PHP Code:
 MYSQL mysql;
    MYSQL_RES *mysqlres;

    mysql_init(&mysql);
    if (mysql_real_connect(&mysql, "127.0.0.1", "root", "", "server", 0, NULL, 0) == NULL)
        return 1;

    if (mysql_query(&mysql, "select * from accounts") != 0)
        return 1;

    mysqlres = mysql_store_result(&mysql)
    if (mysqlres == NULL)
        return 1;

    if (mysql_num_rows(mysqlres) > 0)
        std::cout << "good" << std::endl;

    mysql_free_result(mysqlres); 


What am I doing wrong? If I don't call mysql_free_result(), the next time I query the database my program hangs.

Not really a MySQL problem; should probably be in the C/C++ forum. Having said that, we can't see all your code so we have no idea if you've got a bad query, etc.

Are you trying to reuse the mysqlres pointer?

No, that is the entire code. I left out the main and all of that to make it more of a mysql question.
