[debian-mysql] Bug#1030510: mariadb: FTBFS on s390x: timeout

Sun Feb 5 21:02:47 GMT 2023

After restarting the build there is no longer a timeout, but a crash:

main.plugin_auth 'innodb'                w1 [ fail ]  Found
warnings/errors in server log file!
        Test ended at 2023-02-05 09:41:56
line
Attempting backtrace. You can use the following information to find out
^ Found warnings in /<<PKGBUILDDIR>>/builddir/mysql-test/var/1/log/mysqld.1.err
ok

 - found 'core' (0/5)
Core generated by '/<<PKGBUILDDIR>>/builddir/sql/mariadbd'
Output from gdb follows. The first stack trace is from the failing thread.
The following stack traces are from all threads (so the failing one is
duplicated).
