    Bug #20144839 AFTER UPDATING TO MYSQL 5.6.22 SERVER
                CRASHES ON EVERY START ATTEMPT

    Description:
    ------------
    push_warning_printf function is used to print the warning message
    to the client. So this function should not invoke while recovering
    the server. Moreover current_thd is NULL while starting the server.

    Solution:
    ---------
     - Avoiding the warning to be printed while recovery.
    This patch already pushed in mysql-5.6.
