      Description

      MariaDB crashes during queries trying to read, delete or update a row.
      For exemple the query:
      "select id_versao_secao_documento,id_secao_documento,id_usuario,id_unidade,dth_atualizacao,versao,sin_ultima,conteudo from versao_secao_documento where versao_secao_documento.id_secao_documento IN (5547809) and id_versao_secao_documento = 7160696"

      2022-04-28 16:43:41 16 [ERROR] [FATAL] InnoDB: FIL_PAGE_TYPE=0 on BLOB read file ./dbpro_10080_sei/versao_secao_documento.ibd page 13654973
      220428 16:43:41 [ERROR] mysqld got signal 6 ;
      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: 10.5.15-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 = 467872 K bytes of memory
      Hope that's ok; if not, decrease some variables in the equation.

      where mysqld died. If you see no messages after this, something went
