From: "tobi at gcc dot gnu dot org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug fortran/17872] New: gfortran accepts 255_1 as integer constant Date: Wed, 06 Oct 2004 22:48:00 -0000 [thread overview] Message-ID: <20041006224848.17872.tobi@gcc.gnu.org> (raw) the following compiles without error: integer*1 :: i1 = 255_1 integer*2 :: i2 = 65535_2 end we're using signed integers, so this shouldn't happen. the reason is that gfc_check_integer_range compares the integer against gfc_integer_kinds[i].max_int which is 255 for kind 1, etc. not gfc_integer_kinds[i].huge, which is 127 for kind 1 etc. Changing this might break boz constants (e.g. z'ffffffff'), this has to be investigated when creating a patch. -- Summary: gfortran accepts 255_1 as integer constant Product: gcc Version: 4.0.0 Status: UNCONFIRMED Keywords: accepts-invalid Severity: minor Priority: P2 Component: fortran AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: tobi at gcc dot gnu dot org CC: gcc-bugs at gcc dot gnu dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=17872
