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: 10.7.0-MariaDB
 
key_buffer_size=134217728
 
read_buffer_size=131072
 
max_used_connections=1
 
max_threads=153
 
thread_count=1
 
It is possible that mysqld could use up to 
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 467956 K  bytes of memory
 
Hope that's ok; if not, decrease some variables in the equation.
