--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> --- BTW, when using creduce, if the original is valid or has just one error or something similar, please try to write the script such that it will not confirm a reduction which has also other errors, otherwise you end up with testcases like this which have just too many errors in it.
