Hi! I don't know why, but for some reason this started affecting MariaDB recently. Perhaps something related to the new MariaDB 11.8.1 itself, or a some build tool updated in Debian unstable recently.
Details and workaround described in https://salsa.debian.org/otto/mariadb-server/-/commit/398a34c520351d81fd2d095611d156f34ff95a06
