Description
The minimal test case requires only one command, CHANGE MASTER for a named connection (no errors on an anonymous connection)
cat suite/multi_source/memory_issue.test
eval change master 'slave1'
|
to master_port=$SERVER_MYPORT_2,
|
master_host='127.0.0.1',
|
master_user='root';
|
If it's run in MTR just as ./mtr multi_source.memory_issue, it produces an error
Error: Freeing overrun buffer
If it's run with valgrind, as ./mtr --valgrind-mysqld multi_source.memory_issue, it produces valgrind warnings:

I have also attached the trace file (gzipped), and set up the test on perro.askmonty.org where the problem is reproducible. It's in /home/elenst/10.0-mdev253/, just go there and run the test multi_source.memory_issue. You can do whatever you need with this basedir.
The same mysqld.trace that is attached to this task is also there in /home/elenst/10.0-mdev253/mysql-test/mysqld.trace
