Where is a leak?

  • a 2nd mysql_stmt_prepare() API call checks if the handle status is > INIT, and resets all internal variables and frees buffers.
  • mariadb_stmt_execute_direct() API call will send an additional COM_STMT_CLOSE if the status is > INIT, since the statement id has to be set to -1.
