MariaDB 10.5.8 from glibc-2.30 to glibc-2.32 crash?

I upgraded to slackware-current 2021-01-30 and (non-kernel updates from) 2021-01-31 and have been unable to start MariaDB since 2021-01-30. Specifically, I was at mariadb-10.5.8-i586-1 and failed with mariadb-10.5.8-i586-2, which was described as a recompile against glibc-2.32. I have built with mariadb.SlackBuild on my system and still get the same error, which I have posted to jira.mariadb.org.

Here is the .err:

This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.

To report this bug, see https://mariadb.com/kb/en/reporting-bugs

We will try our best to scrape up some info that will hopefully help
diagnose the problem, but since we have already crashed,
something is definitely wrong and this may fail.

Server version: 10.5.8-MariaDB-log
key_buffer_size=134217728
read_buffer_size=131072
max_used_connections=0
max_threads=153
thread_count=0
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 466473 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

Everything else on this system seems to work. Anybody else have trouble or insight?
