It appears that this issue is no longer being worked on, so we are closing it for housekeeping purposes. If you believe the issue still exists, please open a new ticket after confirming it's present in the latest release.

, "Invalid read of size 8" is not a memory leak, and this error might be reproduced with an ASan build too.
(please also make sure that any server for Valgrind testing is always built with -DWITH_VALGRIND=ON)

Reproduced with upstream 8.0.13 build : https://bugs.mysql.com/bug.php?id=93538
