Tests fail because of

2024-10-14T13:39:17.9041809Z exec:  /home/runner/.onetimeserver/Linux-x86_64/wrapper -debug -mysql-version 5.7 -ppid 2296 -type mysql -- --log-slave-updates --log-bin=master --binlog_format=row --innodb_flush_log_at_trx_commit=0 --server_id=1 --character-set-server=utf8 --sync_binlog=0 --default-time-zone=+00:00 --gtid-mode=ON --log-slave-updates=ON --enforce-gtid-consistency=true
2024-10-14T13:39:17.9043794Z *** buffer overflow detected ***: terminated

which is very likely some issue in wrapper.c, but so far no idea what it is.
