Hello Alboni,

You are absolutly right, We need to count global number of MySqlSession instances. If the number of instances falls to zero we need to call mysql_library_end().

I use a memory profiler called valgrind. I invoke him with following command:

valgrind --tool=memcheck --leak-check=full --show-reachable=yes ./ProgramName

I enclose completed patch for this issue. I have added new static variable to count number of instances (numberOfInstances) of the class MySqlSession.

Sincerely,
Klugier
