Description
When the server is started with S3 engine enabled, it throws LeakSanitizer/MSAN/Valgrind errors on shutdown. It doesn't matter whether S3 is fully configured or whether only plugin is loaded, and whether it was used or not.
To reproduce, just start/shutdown the server with --plugin-load-add=ha_s3, or in case of MTR, run any test with --mysqld=--plugin-load-add=ha_s3, e.g.
perl ./mtr main.1st --mysqld=--plugin-load-add=ha_s3
|
Valgrind and LeakSanitizer return rather meaningless errors (below), MSAN is more readable:
