    Description

      If you call SQLGetInfo(SQL_IDENTIFIER_CASE) and pass a short (the correct size for SQL_IDENTIFIER_CASE), then the MariaDB 32bit ODBC interface will corrupt memory because it assumes (incorrectly) that SQL_IDENTIFIER_CASE is a long. Note that this is not a problem with the MySQL interface.
