             Bug #: 56758

           Summary: Missing bounds check for explict-size arrays (+

                    character scalar storage association)

    Classification: Unclassified

           Product: gcc

           Version: 4.9.0

            Status: UNCONFIRMED

          Keywords: diagnostic

          Severity: normal

          Priority: P3

         Component: fortran

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

        ReportedBy: bur...@gcc.gnu.org





NAG detects it and prints:



Actual argument for dummy array X too small -

3 elements instead of 5



call foo(["a","b","c"], 5)

call foo("abc", 5)

contains

subroutine foo(x,n)

  character :: x(n)

end subroutine

end





For constant length, the compiler already does so at compile time:

Warning: Actual argument contains too few elements for dummy argument 'x' (3/5)
