--- Comment #6 from Tobias Burnus <burnus at gcc dot gnu.org> --- (In reply to Jakub Jelinek from comment #5) > This should hopefully fix it. Looks good to me. For the testcase of comment 1, it also gives the expected run-time diagnostic: test.f90:19: runtime error: signed integer overflow: 809078955 * 65539 cannot be represented in type 'integer(kind=4)'
