    Description

      Following mineur update from 10.9.5 to 10.9.7 the attached query will crash on the updated replica but also when executed in command line .

      Server version: 10.9.7-MariaDB-1:10.9.7+maria~deb11-log source revision: 33fd519ca7318cd85bee56e8f79df4608ead194e

      read_buffer_size=1048576
      max_used_connections=1
      max_threads=65636
      thread_count=12
      It is possible that mysqld could use up to 
      key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 201930294 K  bytes of memory
      Hope that's ok; if not, decrease some variables in the equation.
      Thread pointer: 0x7f74f0c071d8
      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...
