Present in 10.5+ only, both in debug and optimized.

SHUTDOWN;

Leads to (ref error log after shutdown):

11.0.1 f2dc4d4c10ac36a73b5c1eb765352d3aee808d66 (Debug)
2023-02-18 14:22:07 0 [Note] /test/MD180223-mariadb-11.0.1-linux-x86_64-dbg/bin/mariadbd: Shutdown complete
Warning: Memory not freed: 280

In all affected versions.

No UBSAN/ASAN issues observed.

I tried to make this work under MTR for some time, but failed. AFAICS ftm, this issue can only be reproduced in a client, not in MTR, not even when using the CLI via MTR i.e. --start-and-exit.

As such, you will need to start mariadbd and then mariadb manually/directly to reproduce.
