Bug#13608112 - 64048: MYSQL_PRINT_STATUS() MISSING FINAL FFLUSH()
  
  Analysis:
  While printing debug information, memory related information and event
  related information were written to buffer after flushing it. Because of this,
  these information were getting printed when we do the next flush.
  
  Fix:
  Instead of calling fflush() before writing memory and event
  information, calling it after memory and event information.
