Server crash in TABLE_SHARE::init_from_sql_statement_string upon table discovery with non-existent database

    XMLWordPrintable

    Details

      Description

      If you create a ENGINE=Connect Table_Type=ODBC Table, and try to save it to a Non-Existant Database, the Server Crashes.

      For example, the following query causes the Server to Crash, whenever the Database ("db_name_non_existant") in which the created Connect ODBC Table to be saved does not exists:

      CREATE OR REPLACE TABLE db_name_non_existant.tb_name_new
           ENGINE=CONNECT
           TABLE_TYPE=ODBC 
           CONNECTION='dsn_name'
           OPTION_LIST='UseDSN=Yes,User=user_name,Password=*******************'
           TABNAME='db_name.schema_name.tb_name';      
      

      The Error Log Backtrace is the following:

      180918 15:30:56 [ERROR] mysqld got exception 0xc0000005 ;
      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: 10.3.9-MariaDB

      read_buffer_size=262144
      max_used_connections=12
      max_threads=65537
      thread_count=4
      It is possible that mysqld could use up to 
      key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 1560 K  bytes of memory
      Hope that's ok; if not, decrease some variables in the equation.
