A related issue: we print warning: overflow in conversion from 'int' to 'char' changes value from '300' to '','' in the test in the patch. That's because the value is 44, it's type is char, and the ASCII value for ',' is 44. So I think we should convert values of char type to int for the diagnostic. Marek
