             Bug #: 55591

           Summary: strict-aliasing & Fortran

    Classification: Unclassified

           Product: gcc

           Version: 4.7.3

            Status: UNCONFIRMED

          Severity: normal

          Priority: P3

         Component: fortran

        AssignedTo: unassig...@gcc.gnu.org

        ReportedBy: joost.vandevond...@mat.ethz.ch





As suggested in http://gcc.gnu.org/bugzilla/show_bug.cgi?id=55585#c5



Richard:

GFortran could enable strict-aliasing unconditionally if it likes (even

at -O0).



I think this makes sense given the Fortran semantics and the way people usually

code in Fortran. Given this is the default at -O2 already, I think

-fstrict-aliasing is well tested.
