      Description

      If a user erroneously doesn't specify a DSN name in the connection string, e.g. like this:

      drop table if exists t1;
      create table t1 engine=connect  table_type=odbc connection='' catfunc=Tables;
      select * from t1;

      It crashes with the following stack trace:
