The exercise just tells me to add two larger and larger numbers and see when an exception occurs. I have just compiled my program with gnatmake with no options, and I am using gcc 3.1 . When the numbers get large enough, the result is just a negative number because of wrap-around. Shouldn't I get an exception, unless I turn it off? How do I compile for with most checks for debug builds, and how do I compile with everything turned off for performance intensive release builds? /David
