How to repeat:
System where AddressSanitizer includes LeakSanitizer, -DWITH_DEBUG=ON -DWITH_ASAN=ON,
./mtr --debug-server innodb_bug70867

Hello Laurynas,

Thank you for the report and feedback.
Confirmed that tests are failing, innodb_bug70867 with "mysqltest: At line 26: command "$MYSQLD_CMD --innodb_data_home_dir=$MYSQL_DATA_DIR/tmpdata $args" failed with wrong error: 23" etc. Nothing much logged to the error log.

Thanks,
Umesh
