I disabled these tests in https://salsa.debian.org/mariadb-team/mariadb-server/-/commit/f3b99c24d2577b35530e6106cb527cc94cb1e061 and thus these failures are no longer visible in the 1:10.11.5-2 upload.
However several other tests now crashed: main.partition_order main.func_str main.func_like main.func_math main.group_by main.group_by_null main.features main.type_datetime main.xml See detailed stack traces in https://buildd.debian.org/status/fetch.php?pkg=mariadb&arch=sparc64&ver=1%3A10.11.5-2&stamp=1696744591&raw=0
