      Sorry, we probably made a mistake, and this is a bug.
      Your assistance in bug reporting will enable us to fix this for the next release.
      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: 11.3.2-MariaDB-1:11.3.2+maria~ubu2204 source revision: 068a6819eb63bcb01fdfa037c9bf3bf63c33ee42
      It is possible that mysqld could use up to
      key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 468064 K bytes of memory
      Hope that's ok; if not, decrease some variables in the equation.
      Thread pointer: 0x0
      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...
      stack_bottom = 0x0 thread_stack 0x49000
      Printing to addr2line failed
      The manual page at https://mariadb.com/kb/en/how-to-produce-a-full-stack-trace-for-mariadbd/ contains
      information that should help you find out what is causing the crash.
