I think you've misdiagnosed the problem.

If driver_ is 0, it means you didn't connect to the database successfully.

Coming at it from the other side, I modified examples/ssqls1.cpp, 
dropping an 'x' in at the end of the query string, and got this message:

	Query error: Table 'mysql_cpp_data.stockx' doesn't exist

That indicates that the query error is being detected correctly and 
throwing the right exception.

Try to modify one of the examples to show your symptom, or boil your 
code down to something very short that shows the symptom using the 
sample database.
