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.

It is possible that mysqld could use up to 
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 63769 K  bytes of memory
 
Hope that's ok; if not, decrease some variables in the equation.

Attempting backtrace. You can use the following information to find out
 
where mysqld died. If you see no messages after this, something went
 
terribly wrong...

Core pattern: core

Reproducible on 10.5+.
The test case is not applicable to 10.4 due to the use of RENAME KEY.

Hmm. It's strange that Mroonga doesn't support inplace RENAME KEY (https://github.com/MariaDB/server/blob/10.5/storage/mroonga/ha_mroonga.cpp#L14619-L14627 doesn't include ALTER_RENAME_INDEX) but the backtrace shows that inplace ALTER TABLE is used...

Ah, I got it. Could you apply this?

(This was already fixed in upstream.)
