In sql/rpl_slave.cc line7887, there is 
if (save_buf != nullptr) buf = save_buf; 

However, the local variable buf is not unused any more in this function. 

Is there anything missed from this function that should make use of this buf assignment?

How to repeat:
It's in mysql-8.0.21

Hi Mr. Zhong,

Thank you for your bug report.

I have analysed the entire code and I can't find a justification on why is that part line necessary, at all.

This is , however, a very low priority bug.

Verified as reported.
