Reproduced in CentOS 7 and official MariaDB 10.3 Docker container
Description
When running the specified stored procedure twice in the same mysql CLI session, MariaDB crashes without providing an error to the error log (the session simply sees ERROR 2013 (HY000): Lost connection to MySQL server during query).
To reproduce-
- Setup a Linux environment with MariaDB 10.3 installed/running
- Ensure at least the following is configured in my.cnf (or similar)-
[server]lower_case_table_names=1
- Create a new database called test (assuming one of the same name doesn't exist on your system already)
- Import the contents of 35872.sql (attached to this issue) into your new, test database
- On the mysql CLI...
USE test ;
CALL YAR_FUNC(str_to_date('2019-07-01', '%Y-%m-%d'),str_to_date('2019-10-01', '%Y-%m-%d'),0,'TEST_ANY_80_2','--MA--','Branch/Subsidiary','Locomotive Branch','GB_A_MOP_GENERAL_XTTY') ;
CALL YAR_FUNC(str_to_date('2019-07-01', '%Y-%m-%d'),str_to_date('2019-10-01', '%Y-%m-%d'),0,'TEST_ANY_80_2','--MA--','Branch/Subsidiary','Locomotive Branch','GB_A_MOP_GENERAL_XTTY') ;
- Note that you can make other queries between the two CALL YAR_FUNC commands and the outcome will remain the same
- You should immediately experience a loss of connectivity, and if you check MariaDB's error log you should see evidence of a shutdown/restart
