Hello Laurynas, Thank you for the report and feedback. I tried reproduce this on almost all available instances(OL7, Ubuntu, CentOS7 etc with src debug builds - mysql-boost-8.0.4-rc.tar.gz) but not seeing any issues. Could you please provide exact cmake with the options used? Thanks! Regards, Umesh

Umesh - I have lost the exact CMake invocation for this particular reproduction. In any case this should be load-, not cmake-related, and I have suggested an IMHO very plausible cause and fix in the bug report, it could be handled as a testcase improvement request then.

Thank you for the feedback. Verifying as a testcase improvement request. Regards, Umesh
Description: Intermittently: rpl_gtid.rpl_multi_source_block_receiver 'stmt' w1 [ fail ] Test ended at 2018-02-05 01:34:28 MTR's internal check of the test case 'rpl_gtid.rpl_multi_source_block_receiver' failed. This means that the test case does not preserve the state that existed before the test case was executed. Most likely the test case did not do a proper clean-up. It could also be caused by the previous test run by this thread, if the server wasn't restarted. This is the diff of the states of the servers before and after the test case was executed: mysqltest: Results saved in '/mnt/workspace/mysql-5.7-param/BUILD_TYPE/debug/Host/min-centos-7-x64/build/mysql-test/var/1/tmp/check-mysqld_2.result'. mysqltest: Logging to '/mnt/workspace/mysql-5.7-param/BUILD_TYPE/debug/Host/min-centos-7-x64/build/mysql-test/var/1/tmp/check-mysqld_2.log'. mysqltest: Connecting to server localhost:13001 (socket /tmp/2cBaIuT0W1/1/mysqld.2.sock) as 'root', connection 'default', attempt 0 ... mysqltest: ...
