--- Comment #8 from janus at gcc dot gnu.org --- (In reply to Harald Anlauf from comment #7) Thanks for checking, Harald. So XLF and NAG agree with gfortran on comment 6. That's the easy part (since the interpretation of these cases is explicitly given in the standard). Apparently ifort and pgfortran are buggy in this area. Could you also check what XLF and NAG report on comment 1 (which is a somewhat more questionable case)?
