Hello, I am using a threaded C program and each thread creates its own connection to mysql database using mysql_init(). When I run Valgrind on the program it reports that there has been a small leak stemming from several mysql_init and one mysql_real_connect. I have read http://www.mysql.com/doc/en/Threaded_clients.html but despite adding my_thread_init(), my_thread_end() and linking against mysqlclient_r a leak is still reported. Here is some of the output valgrind produces:

Is this report spurious? If not what am I doing wrong to cause this leak? I am running "mysql Ver 11.18 Distrib 3.23.56, for pc-linux (i686)" on RedHat 7.3.
