------- Comment #1 from jakub at gcc dot gnu dot org 2009-04-29 14:04 ------- That's by design. Obviously there are so many possible combinations that you can't exhaustively test them all, that's why this test randomly chooses some. You can pass -n count to the generator to generate more (or fewer) tests, instead of the default 3000.
