MariaDB crash on calling function

    XMLWordPrintable

    Details

      Description

      One of our customer observed server crashes, when calling a function, which invokes two other functions, involving some tables and a view.

      This behavior is observed at the 10.3.24, 10.4.14 and 10.5.5 (the latest releases). Also, important to note customer has provided the related functions, tables, views details, through which I can locally able to reproduce the issue at our latest releases.

      Attached is the dump.sql having all related functions, tables, views. Also, attaching full error log(maria.err), all threads backtrace(mysqld_bt_all_threads.txt) output.

      To reproduce:

      * Install 10.3.24 or 10.4.14 or 10.5.5(latest release) 
      * restore the data - dump.sql
      * At server.cnf put
      lower_case_table_names=1
      log-error=mariadb.err
      core-file
      * Start the server
      * execute below SQL
      select  FN_SPM_CHK_BCD_PUBL_TEST('1', '20200910') as aaa
      

      Error log output:

      201007  8:56:58 [ERROR] mysqld got signal 11 ;
      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: 10.3.24-MariaDB-log
      key_buffer_size=268435456
      read_buffer_size=8388608
      max_used_connections=1
      max_threads=1002
      thread_count=9
      It is possible that mysqld could use up to
      key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 16701465 K  bytes of memory
      Hope that's ok; if not, decrease some variables in the equation.
